How relevant is a match with one 'long block'?
« on: Sunday 14 May 17 19:51 BST (UK) »
Hello
I've recently completed a Family Tree DNA test using their 'Family Finder.' In my matches there is one where we have 63 shared centimorgans with a 42 long block at chromosome 5-this has placed the match as 2-4 cousin range.

The 42 block is by far the longest block I have. I have been able to find a ancestor link with a match where we shared 74 centimorgans with the longest block of 18 so 42 seems quite significant. unfortunately there is no family tree to compare and she would only give a few surnames via email. One of my grandfathers and a great grandmother was illegitimate so this could be an link.

Is it worth contacting her further with the illegitimate lines in mind or is a block of 42 not as impressive as I first thought?!

Thanks for reading my rambles  :)

It's a pain when people don't post trees.  The sharing seems to be all one-way.

Estimated 2nd - 4th cousin means that you're looking for a common ancestor at GGP to 3xGGP.  Since you have known illegitimacy at that sort of level I'd say it's worth pursuing but it might be an uphill struggle.

If it's proving difficult to get names out of your contact, try locations.  Just as useful if not more so.  Also do a google search on their email and any names you do know, in case they have a tree posted elsewhere.

To put your 63/42 into perspective, my father has a proven 4th cousin (est 2-4C) who shares a total of 83 with longest block 53 and my mother a proven 1st cousin once removed (est 2-4C) with total 125 longest block 52.

best wishes

Thanks Jane
Really useful advice and tips. Your examples of proven links also give me some idea of what the longest block could relate to.
