Hello cousin Nathalie,
Yes, Elizabeth Corse was the dau of Elizabeth Catlin and James Corse who were married in Deerfield,MA in 1691. They also had 2 sons, James and Ebenezer who were not taken captive and raised large families. The Father, James Corse is belived to have come from
Lanark, Scotland...but to this day, there has been no trace of just who his parents might have been even tho many people have spent years trying to find out. The mother Elizabeth was the dau of John Catlin and
Mary Baldwin. John was the son of John Catlin and Isabelle WARD.
Mary Baldwin was the dau of Joseph Baldwin and Hannah Whitlock who were married in High Wycombe, England in 1636. They came to Boston in 1638 on the ship Martin along with many other Baldwin relatives including Joseph's brothers, Timothy and Nathaniel.
Elizabeth Corse was 8 years old when taken to Canada along with her mother..but the mother died along the way. Also taken were Elizabeth's cousins, The children of Thomas French and Mary Catlin..2 boys and 3 girls, Freedom, Abigail, and Marthe.
