I've been researching the Northam and related families for a few years now and you'll no doubt be interested to know that we appear to be related. My 3 x great grandparents were William Northam and his wife Eliza (nee Willis)of Pointington, the very same people you have mentioned in your message !! I am descended from their son, Fred Northam.I don't know how much you know about this and related families but I have a fair amount of info. There appears to be a lot of inter-marriage going on which makes for a rather tangled, and interesting, family tree. Look forward to hearing from you and maybe we can share some info. on our family.
