Karen, I would need testing of both of your father's parents descendants before I would even begin to guess on this one. In other words the answer is unlikely. Sam Hi Ann Thank you for the image. Dad and I have tested and the longest segment we have in common is 267.21 cMs with almost 60,000 SNP's, so would it be wrong to guess that the longest segment is his surname ? The next longest is 206.75 cM's most likely a grandparent line? All other segments are under 200cMs., with less than 50,000SNP's

The longest segment between a parent and child is typically the longest chromosome (chr 1) unless there is a mirodeletion which cuts it into more than one segment. There is no association between this and surname.
