Is this sufficient evidence?

[Burgess/Crawford]

I am attempting to use DNA testing to solve a very old family mystery. My ancestor used the name Burgess when he migrated to Australia in 1838 but a recently discovered 1838 diary suggests his real name was Crawford.
I had a 25 marker test conducted but no matches were found with any families. However using Ysearch, only one match appears. This match is with a CRAWFORD family in Canada. However the match is only 9 out of 12 markers. Is this sufficient evidence for me to say conclusively that our real name should be CRAWFORD, rather than BURGESS?

The answer is no. If you use the tool at http://dna-project.clan-donald-usa.org/tmrca.htm , you see that with a 9/12 match, the most likely common ancestor of two cases in the same haplogroup lived 72 generations ago.

But matching some other case on more markers, with a common ancestor within the era of British surnames, might solve your mystery.

Oh wow that is interesting. 9/12 and the same surname.

I read in another thread, just a minute ago, that a father and son differed by 2 markers.

What if you and the Canadian Crawford both upgraded to 67 and you match 64/67? There is always that chance. Good luck.


I don't know my fathers ydna, but I found someone with the same surname who lived just miles away from where my great grandfather was born. And I guess my father would have the same ydna (I think it was ydna I).

I have only just joined this forum and am still waiting on DNA test results.

My family came to Australia from Scotland (Shetland Islands) possibly around the 1930-1940 time and settled in NSW at Mudgee. My great grand father, Robert Crawford, was a gold prospector and worked in the gold fields around Mudgee and Orange areas.

My grandfather, also Robert Crawford was born in Mudgee in 1858.

I am wondering whether there is a connection between your family line and mine. I am happy to share any information I have, although it is limited.

I am not aware that Crawford is / was a Shetland surname. If so quite rare, or maybe only resided there a short time. Your ancestors should be found in the comprehensive genealogical database that covers all families in Shetland: www.bayanne.info/Shetland
