Today’s information sheet turned into a bit of an epic six-pager – and that is just part one of the story!
If you are working with DNA results you will spend a lot of time puzzling over where your new-found matches fit into your family tree. Some of them will be very straightforward, maybe family you already know, or people who share a distinctive surname that you recognise. Other DNA matches will take you weeks or even months to find a place for, or may be a perpetual mystery!
In order to work out where people belong in your tree you will need a good understanding of the way that family relationships are described. The descriptions for close family members are part of everyday language, but once terms such as “half-cousin” or “third cousin twice removed” start coming into play it gets more complicated.
The fact that your Mum and her sister have different fathers may not make any difference to you whatsoever on a day-to-day basis – she is “just” Aunty Mabel to you. However, if you want to use DNA results to work out where people belong in your family tree, factors such as having one parent in common will be reflected in the amount of DNA that people share and therefore affect the possible relationship between you.
Part One can be found by clicking the link below – Part Two will look at how much DNA you can expect to share with different relatives:
