Hi Roseanne:The connection to the peerage was through the husband of Sidney Sarah Rothwell, my great maternal grandfather, Philip Eustace Buck, and was Sir Robert Walpole. I have a plethora of info there.I think your line is the same line of a gentleman with whom I exchanged info about ten years ago who is or was from Bancroft, Ontario.I don't have my genealogy info in front of me at the moment.
I have a copy of interesting correspondence between Philipa Eustace Bucke and a gentleman requesting information from PEB re Charles Alison in connection with the latter's Will. Some of the Bucke line have Rothwell/Alison first names.Names were certainly recycled in those days.
Alison passed away near Peterborough, Ontario which is what I consider to be my hometown, even though I was born in Alberta.The long obituary was from the newspaper which still is in operation in Peterborough, in name anyway.
