I don't know if my information is correct or not, but I have Jennies as being born 18 August 1835. The death date I have for her is 28 May 1921. According to these dates Jennie was 85 years old. She would have been 86 in August. That is if the dates I have are correct.
Jennies first husband was Leon Benoit Alexandre Duclos. It is said he left home and family to fight in the Civil War and was never seen by any family member again. I have a military record that says he deserted the army in January 1863 at Napoleon, Arkansas. Rumor has it that he went to Canada.
