I have been collecting Cudmore information since the early 1990's, with my original focus being the Cudmore families in Prince Edward Island. That has grown to adding bits and pieces from every contact I have made and is now up to 8700+ individuals.
As I find links/connection back to the main branch I add them in. There are as always several "orphan" Cudmore's and I still have two large branches that are not yet connected to the main tree. I keep just adding to the information I have as I find a new source.
At a guess I have added to the information on your branch, I was in touch with Jan Boncheff and was saddened to hear of her passing. She had a great deal of Cudmore history.
I can send you a copy of the information I have on your branch with my notes and perhaps it will fill in a few more blanks for you. Let me know and I'll help if I can.
