Sorry, but the information you have is a repeat of the "Roloson's Blunder"...in her 1981 book on the Catlin family,(she died in 1974 and never had a chance to proof-read the manuscript) Louise Catlin Cleaver Roloson was confused about the relationships...she has James' son as his father
There is only one Sergeant Ebenezer Corse and he is the son of James Corse...his wife was Sarah French, not Sarah Warner, tho she is the daughter of Jonathan French and Sarah Warner...See the extensive work recently done by John DuLong
regarding the "origin if James Corse"...great web page under www.habitant.org. thanks for responding but please try to correct this error that has been floating round even by Churchard on his web page... thank You
