Great to hear from you. If I've got your line right is it the one that goes back to John Kingman and Ann Wheeler, living in Norbeton, Surrey in 1841? That is as far as I've got on that Kingman line.
I have had two Kingmans so far join the DNA project, along with some Kinsmans and Kingsmans. They turn out to be not related, but intriguingly both are haplogroup J2 - not particularly common in the UK.
If you could contact me direct at docwatto AT hotmail.co.uk then we can set things up for you to join the group.
