FamilyTreeDNA Family Finder Autosomal DNA test - Update July 2013

Clip art from Microsoft Office Clip art. 
Family Tree DNA have announced that they will keep the US$99 sale price for their Family Finder test. Have a look at +CeCe Moore's Your Genetic Genealogist blog and Roberta Estes' DNA Explained blog for the news.

Cousins, can you help?
With this new lower price, I'd like to invite and encourage any of my relatives who may be interested in genealogy, from any branch of my family, to please consider taking the Family Finder test.

As one of my main goals at the moment is to write the history of my Fullerton ancestors, I am particularly interested in asking descendants of my 3 x great grandparents William Fullerton and Mary Dunn to consider taking the Family Finder test to help gather clues to discover if there is any truth in the Fullerton families’ ‘Spanish’ ancestor story. Family Finder results for myself and my Dad appear to suggest we could have some ancestry from somewhere other than the British Isles. To make more sense of these results, I need to ask more Fullerton relatives if they would be willing to take the Family Finder test.

Why ask known cousins to take the Family Finder test? 
FTDNA Chromosome Browser: I can now ‘map’ one side of
 this segment of my uncle’s DNA as having been
 inherited from our 4 x great grandparents from Essex, England.
By comparing the segments of autosomal DNA where a known cousin matches with myself, my Mum, my Dad or my uncle, I can begin to ‘map’ particular segments of our chromosomes to particular ancestors. As an example, my uncle matches with some known fourth cousins. Their common ancestors are my fourth great grandparents from Essex, England. I can now ‘map’ one side of this segment of this chromosome as having been inherited from those ancestors. Anyone who matched on this same segment could be related to me through those ancestors.

The following blog posts give some good examples of how useful it is to test as many known relatives as you are able.
What should you know before you decide to test?
  • Autosomal DNA inheritance is random. The greater the distance of relationship between two people the less chance that they share DNA. The Autosomal Statistics page on the International Society of Genetic Genealogy (ISOGG) Wiki shows the average percentage of DNA shared between relatives. We may share DNA or we may not, it is a matter of chance. As an example, myself and my Mum did not match with known fourth cousins that my uncle matched with. 
  • DNA tests for genealogy are a long term investment. You may not learn anything very useful today or tomorrow, but as the database grows, as more people (including known relatives) are tested in the years to come, the answers to many genealogy questions may appear. The Family Finder test has a once off payment and no ongoing subscription costs, so it is a future genealogy investment.
  • The Family Finder test at Family Tree DNA is for the purposes of genealogy research and is not a DNA test for health. 
  • Each person who takes the Family Finder test has to do so of their own will and sign the consent form so that their contact details can be visible to their matches. Please see Privacy and FTDNA's Privacy Policy and Terms of Service
  • Have a good look at the Family Tree DNA FAQs. Particularly read the FAQs for Using the Test Kit (and DNA Test Kit Instructions), myFTDNA 2.0 User Guide: Family Finder and Understanding Results: Family Finder

What have I learnt from the Family Finder test so far?
As I mentioned above, I realise that the Family Finder test is a long term genealogy investment and definitely does not provide instant answers to genealogy research problems.

Some of the interesting things I have discovered so far are:

  • Among my uncles matches are known relatives, descendants of my 4 x Great Grandparents from Essex, England. 
  • Patterns among matches are definitely appearing. For example, I have identified clusters of matches with whom the common ancestor is very likely to be from Ireland. For example, there is a County Galway cluster among my Dad's matches. Some of the matches who match on this segment have only County Galway surnames and locations listed in their known ancestry. I can estimate (but ofcourse not be 100% sure) that this cluster of matches (who all match each other) are related to my Dad through his Joyce, Guinane and Hogan ancestors. 
  • Admixture tests at Gedmatch suggest that my Mum has distant Finnish ancestry. Indeed, she and my Uncle actually have some distant Finnish matches through Family Finder. I would never know this without genetic genealogy. Fascinating! Now I wonder, which branch of her family did this possible Finnish ancestor come from?
  • My Dad has some interesting distant matches too, including Germans, Swedish and Sicilians. Could these matches have a common ancestor from beyond a genealogical timeframe? Possibly. But it is very interesting nonetheless!
The numbers
As of early July 2013 the total number of Family Finder matches is as follows:
  • Me - 228 (105 in common with Dad, 74 in common with Mum, 42 in common with my Uncle). That doesn't add up, I know. I have a number of matches who match neither Mum nor Dad. This is an interesting phenomenon mentioned in this FAQ on the Family Tree DNA web site. My interpretation? Mum and Dad both have Scots ancestors from adjacent counties in Ulster, as well as Irish ancestors from adjacent counties in Munster, and therefore probably share a common ancestor way back somewhere (as we all do). 
  • Dad - 239 (105 in common with me, 3 in common with Mum, 4 in common with my Uncle) These matches in common with my Mum and Uncle are likely just a coincidence and are probably related to each in different ways. 
  • Mum - 233 (74 in common with me, 93 in common with Uncle, 3 in common with Dad).
  • Uncle - 206 (42 in common with me, 93 in common with Mum, 4 in common with Dad).
