Gadget, you said =cluster as calculated by My Heritage or the Leeds method?

What us the difference? I'd never realised there was one.

I was referring to which was used to generate the clusters.

Good morning. Consider that your second cousins will match your common ancestry at the Great Grandparent level. You have 8 of them. Second cousins are descended from grand Aunts or Uncles, (Siblings of your grandparents) so possibly they may have different parents than each other. DNA is quite variable from each source and is not generally an average percentage as it is passed down. All normal.

John -

That's very interesting.

There is almost a 100 cM difference in the amount of DNA they share with me.  We all share 9.9cMs - surprisingly little.

Your explanation has been very helpful Gadget.

Gadget, thanks.  Clear now. What's the difference between shared matches with two others and triangulation?  They seem the same to me, but my list of matches highlighted the triangulated ones.

I think it's that all of them match each other and you. I don't used the clusters very often.
