I saw the following query on the Quebec Family History site but have not been able to contact the person who placed it there.In any case it ties two Penetang Gendron lines together if the information is correct.
GENDRON, Louis Charles, born c1794, possibly St. Martin, Qc., died 1858 Penetanguishe, ON. Married Angelique ALGEO/AJO/HALLIO. Had a half-brother, Michel GENDRON, born c1828, St. Martin, Qc., died 1874 Penetanguishene, ON. He married Amanda JUDSON. Seeking information on their parents and siblings.http://www.qfhs.ca/srch_queries_1.html#ghttp://www.qfhs.ca/srch_queries_1.html#g
My son-in-law is descended from Michel and Amanda and my wife is descended from Amanda's sister, Sarah Ann Judson.
