I never knew he was a Napier cousin until I started doing the Napier ONS. I started working on all his lines going up to connect him to the tree (on my Ancestry account) but my main purpose was to connect with the Napier line which I have done. Turns out he's my 12th cousin 3x removed! :-)
If anyone wants to work on his others lines feel free. I can give you the names I have so far if you need them.
