Not knowing much about the wife, Mary SAUNDERS (1756-1828), I used a lot of resources to find out the names of her parents and grandparents. Her mother was a BABCOCK descendant and that went along quite well as there are still a lot of Babcocks in that area of Rhode Island.
However, her father's parents are another story. Her father was William SAUNDERS who was named for his father William SAUNDERS. The elder William SAUNDERS (1713-1772) had a wife named Mary VARS.
Listening to my father's stories about Westerly, I knew there was a VARS drug store in Westerly, RI and there is a street there named for this family.
Soon, I disovered that Mary VARS had parents named Isaac VARS and Rebecca LARKIN. I thought that they must be the immigrant ancestors. But, they are not. I thought Isaac was born in Westerly but I guess he was not. He was born in FRANCE to a LORD JOHN de VARS. Yikes.
Do I believe this story written by a descendant? [I am taking a small clip of the page and the title page for you to look at.] Is this believable? Where do you draw the line (a duel pun) at family stories?
