Making DNA work FOR YOU
JOHN WRITES: Dear Karen, As I was reading your DNA Workshop in the February edition of Family Tree, I thought about asking for clarity on the WATO (what are the odds) tool. I turned the page and there it was! At first. I have tried to follow the steps you give, but I am still unclear about some basic things. Please can you help?
I have taken a DNA test with Ancestry, and have clustered my DNA matches into groups, with some groups verified as ancestors or descendants of each set of 2x great-grandparents (eight groups in theory). Many of my suggested common ancestor matches have been verified from paper records.

The match has a private tree, does not respond to messages and may no longer be active on Ancestry. I have built a ‘quick and dirty’ tree for XX using local knowledge and records, but have not found any possible DNA link in five generations. I want to use WATO to examine possible locations for XX in my tree.
So, I have 18 other
