Dear Collette:
I have some Leadbetter relatives with the names Raymond and Henry, not sure about the Kenny though. I have the book Leadbetter Records by J.E. Ames with all of the early history of the Leadbetter's who came over to Dorchester, MA from England in the 1600's so, maybe with that or other research I've got we can help you. Feel free to email me @ tribarkin@charter.net and I'll help in any way I can.
All The Best,
Jody Champlin
daughter of
Barbara Louise Leadbetter
