So I was trawling my Ancestry DNA matches tonight and thinking how I'd never figure out most of them.
My smallest cM match connection where I am able to document how we're related is a third cousin once removed with whom I share 10cM over 2 segments.
With and without DNA, I have at this stage confirmed a fair few 4th cousins and 4C1Rs, but haven't made the leap to a 5th cousin yet for myself.
I was amazed that Eneclann were able to document an 8th cousin of Barack Obama's. What's the best other people have managed on Irish lines?
