I share from 25 to 50 cM of DNA over one to four gene segments with individuals from four families who trace ancestry to Alexander Boyce (Boyce-2300) and Olive (Bacon) Boyce (Bacon-5544) of Westmorland County, New Brunswick (on the Northumberland Strait.) The most likely conventional relationship for those shared gene segments would be if Letitia Doyle's mother (my 3G-grandmother) was a sister of either Alexander Boyce or his wife, Olive Bacon. I have been unable to identify Letitia Doyle's parents, but she was born on Prince Edward Island about 1827. Has anyone found information about a Doyle who might have married a sister of the Boyce couple?
