My uncle "Jimmo and aunty Jeen were living in Lindfield Holm(pronounced"Ham")when I was a wee boy and not so wee....Is it a coincedence that they share the same names as your ansesters? I dont know:both my uncles and father came from Fairys park(pronounced "perk!")and-Oh!Thats in Westrey.
Its a pitty my aunty Jeen is not with us because she was the best at all these things.
I know a bit about the Gunns but couldent tell you about any connections´-Try my cousin David or his niece Angela-they are much better than me..because theyre "on the spot"
