Gale after reviewing the information you sent, I don't believe the scenario you developed is possible or probable. If
Augustin was born 2/25/1745 and his son was born 11/3/1814, then
Augustine would have been 69 years old at his son's birth. More importantly Augustine's wife Marie, who you show as married to
Augustine on 2/15/1768, would have been married to him for 45 years before giving birth to Timothy.
If there is compelling evidence to support the relationships in spite of the dates, please let me know.
