Ancestry.com offer HALF-PRICE
subscriptions ONE DAY ONLY
For just 24 hours, from 9pm
Pacific time (5am next day London time) on Friday November 10th until 9pm Pacific time
on Saturday November 11th, Ancestry.com are offering a 50% discount on all of their subscriptions (it doesn't, sadly, apply to current
subscribers). This is an incredible offer -
Ancestry are not renowned for their generosity, so if you've been biding your
time waiting for an opportunity, this is it!
The discounted price only
applies to the initial period, so clearly there's no point taking advantage of
the offer unless you're going to buy a 6 month
subscription. Your subscription will renew automatically at the standard price,
not the discounted price - but you can cancel your subscription at almost any time
during the first 6 months (you'll still get what you've
paid for, of course). I say almost any time because if you cancel in the first
30 days they'll cancel your subscription and give you a refund, which clearly isn't
what you want having secured such a very special discount!
A World Explorer subscription
gives you access to all the records of Ancestry's worldwide records - indeed you can log-in to
any of Ancestry's sites if, like me, you find it more convenient (the quick links on the home page
vary from one country to another).
Note: the prices quoted do not
include local taxes.

Free access to military
records at Ancestry.co.uk ENDS MONDAY
Until Monday November 13
Ancestry.co.uk is offering free access to millions of UK military records - to
search the records or see a list of all the included record sets follow this link.
Note that you'll need to log-in (or register if you haven't done so previously) but you
won't be required to provide credit card or bank details. Some of the indexes may link
to images at the Fold3 website - my email from Ancestry didn't say that these are
included in the offer - indeed, Fold3 isn't even included in Ancestry's World
memberships, you need an All Access membership (as shown in the image above) - but one
member has reported that her email read differently, though she did have to register separately
at the Fold3 site.
Tip: you can also get free access to Findmypast's more
extensive collection of military records, but only until Sunday - see this article from the last newsletter. The
Findmypast offer includes US, Canadian, and Australian records as well as
British records going back to 1760.

MASTERCLASS:
What to do with your autosomal DNA results
I'm repeating this article from
three months ago because when it was first published I was swamped by emails
from members telling what amazing results they had achieved by following the
simple strategies outlined - and over a million more people have tested in
those 3 months.
Introduction
No matter how much experience
you might have as a family historian, it would be understandable if, when the
results of your DNA test came through, you were completely flummoxed about what
to do next. There's a simple reason for this - we're used to working backwards from
what we already know, so there's a clearly defined path, ie:
find our ancestor's baptism in order to discover (or
confirm) who their parents were, then find the parents' marriage, then find the
baptisms of the parents and so on, working back a generation at a time.
The challenge
But when we're matched with a
genetic cousin, someone who appears to have inherited an identical segment of
DNA, we're faced with a very different challenge. Most of the matches we make
with DNA cousins will be many generations, since we have many more distant
cousins than we do close cousins. The final column of the table below indicates
roughly how many cousins you might expect to find if you and they all took the
Ancestry DNA test:
Based on Table 2 from: Henn
BM, Hon L, Macpherson JM, Eriksson N, Saxonov S, Pe'er I, et al. (2012) Cryptic
Distant Relatives Are Common in Both Isolated and Cosmopolitan Genetic Samples.
PLoS ONE 7(4): e34267. doi:10.1371/journal.pone.0034267
Revised using Ancestry DNA
estimates for the chances of detecting cousins and the expected number of 1st
to 6th cousins for those of British ancestry; the numbers for 7th to 10th
cousins are my own guesstimates
Of course, in practice only a
small fraction of your cousins will have tested - even Ancestry, the biggest
providers of autosomal tests, have only sold 6 million tests - but you can nevertheless
reckon that the cousins you're matched with will be distributed roughly in proportion
to the figures shown above. In other words, over 99% of your matches will be
with relatives who are at best 5th cousins, and could well be 8th cousins or
even more distant.
Tip: Ancestry won't show any of your DNA matches as
more distant than '5th to 8th cousin', but it's very likely that amongst them
there are many who are more distant - possibly as many as half of them. Once
you get beyond 3rd cousins the length of the shared segment(s) is only a very
rough guide to how closely you are related - you could share a 7cM segment with
a 10th cousin, but no detectable DNA with a 5th cousin.
You and your 5th cousin share
the same great-great-great-great grandparents. Now, I don't know about you, but
I certainly can't say who all of my 4G grandparents
were - indeed, I don't even know for sure who all my 3G grandparents were. I've
got several 'brick walls' in the last 5 generations - and most researchers,
including my DNA cousins, are probably in the same situation. Go back another
generation and there are even more gaps - and it just gets worse from then on.
In other words, most of the
ancestors who link us to our DNA cousins are on the other side of a 'brick
wall' - and this could be a 'brick wall' in your own tree, in your cousin's
tree, or even in both trees. What a challenge!
The reward
At this stage it's important
to remind ourselves why we took a DNA
test! Surely the primary reason we tested was to knock down 'brick walls' that
conventional research couldn't breach? If our 'brick walls' have resisted our
efforts for years (or even decades), the opportunity to knock them down using
DNA is surely well worth grasping - even though it will mean that we have to adopt a new and unfamiliar strategy, and utilise somewhat
different techniques?
How to process your DNA matches
I'm going to assume for the purpose of this article that you tested with
Ancestry - but don't stop reading if you tested elsewhere because I'll be
covering techniques you can use at Family Tree DNA and GEDmatch.
At Ancestry you'll typically
have 5000 to 15000 matches with cousins, and of those all but about 1% will be
with 'distant' cousins, ie where the estimated
relationship is 5th cousin or more distant. So the
obvious strategy is to focus on the 1% on the basis that if you can't make head
or tail of those matches, your chance of resolving the more distant matches is
negligible. However, that 'obvious'
strategy would be wrong - and here's what you should do instead......
Strategy 1: search by surname
My experience has shown that a much better approach
is to search the trees of your matches by surname, in the hope of identifying
cousins who have the same surname in their tree as one of your 'brick wall'
ancestors. Here's how to go about it:
Strategy 2: search by birthplace
As you will have discovered
when working through your list of surnames, most of the time the surname of the
ancestors you share with a DNA cousin doesn't appear in both trees - indeed,
it's quite possible that the surname of your common ancestor doesn't appear in
either tree!
The problem is, when your
female ancestors married they generally took their husband's surname. This
makes it more difficult to research female ancestors whose children were born
before the commencement of civil registration, since baptism registers don't
usually give the mother's maiden surname - usually the only solution is to find
the marriage. (By contrast you can continue researching your male ancestors
even if you can't their marriage.)
Of course, this problem
doesn't simply affect you and your research - it affects your cousins too; most
researchers' tree become increasingly sparse with each generation. If you've
only identified 10% of your 256 6G grandparents and your cousins have only
identified 10% of theirs, the odds of finding out how you're related to a 7th
cousin simply by comparing the names in your trees are pretty
remote.
Another way to figure out how
you are related to your DNA cousins is to look for geographical overlaps - and
here's how to go about it:
Strategy 3: look for overlaps with the more unusual
components of your ethnicity
Most readers of this
newsletter have mostly British, Irish, or western European ancestry. But some
of you will have Jewish ancestors, or ancestors from outside Europe, and whilst
ethnicity estimates can be quite misleading, they do provide another way of
analysing your matches.
Here's what Ancestry show for
one of my DNA cousins:
If Ancestry had detected a
Jewish component in my own ethnicity this would be one of the matches I'd be
looking at very closely.
Strategy 4: look for the 'elephant in the room'
Because we all have 'brick
walls' in our trees there are parts of our ancestry that are a closed book -
yet there will inevitably be clues amongst our matches, if only we look for
them. For example, if - like me - you don't know of any Irish ancestors, but
have lots of matches with cousins who do, you might begin to wonder whether one
of your 'brick walls' is concealing a connection to Ireland.
I can't provide you with a
step-by-step guide - it's all about awareness (Louis Pasteur said that
"chance favours the prepared mind").
More tips
Downloading
your DNA results - and uploading them to other sites
Although more people have
tested their autosomal DNA with Ancestry than all of
the other companies added together, everyone can find more matches by uploading
their results to the free GEDmatch site, and those who tested with Ancestry can
also upload them to Family Tree DNA.
Downloading your results from
one site and uploading them to another is a remarkably simple process - just so
long as you know where to start. Ancestry users seem to have the most problems,
though I can never figure out why - all you need to do is log-in, go to your
DNA home page, then click SETTINGS at the top right. On the next page you'll
see DOWNLOAD RAW DNA DATA at the right - click this button, then enter your
password on the pop-up and tick the box below, and then click CONFIRM.
Within the next couple of minutes you'll receive an email with a link 'Confirm Data
Download' - click this link and you'll be taken back to the Ancestry site.
Finally click DOWNLOAD RAW DATA to download the Zip file. Where this file ends
up depends on your browser settings, but mine can be found in the Downloads
folder, so I'd suggest looking there first.
Tip: if your email from Ancestry doesn't arrive check
your spam folder; the address it is sent from is AncestryDNA@ancestrydna.com so
you could try adding that address to your address book.
Uploading your data to
GEDmatch is very easy - simply log-in (or register if you haven't already done
so) then click the Generic Upload
link on their home page:
The only difficult part is
waiting for them to process your data - it could take a day or two before you
are able to search for matches. However if your
initial aim is to look more closely at a match you've found at Ancestry, you
don't have to wait - just so long as your DNA cousin has uploaded their results
and told you their kit number (this is allocated by GEDmatch).
I'll be writing more about
GEDmatch in future newsletters, but there's lots of guidance on the GEDmatch
site, and you’re not going to break anything if you experiment. One word of warning:
not all GEDmatch pages have a link to take you back to the home page, so you
might need to use the browser back button (or else you could open GEDmatch in
other tab).
Tip: GEDmatch are currently working on GEDmatch
Genesis, which is in the beta testing stage (so you can try it out); currently
GEDmatch Genesis offers the only way for those who tested at Living DNA to
search for cousins, although will be offering cousin matching very soon.
In the next full issue….
I've rushed out this update
to make sure that nobody misses out, But there are
some great articles coming up in the next issue, including a case study
featuring discrepancies between birthdates recorded in the baptism register and
birthdates shown on birth certificates. I suspect that some of you will be
surprised by the conclusions of the investigation!
Update 11.50pm (London time): the starting time of the Ancestry sale was originally notified
as 9am but has just been corrected to 9pm (Pacific time) - Ancestry have apologised for any confusion.
