"Jesse Oman Lewis 1st was born Dec 30, 1760. He died February 12, 1869. ... He married Chloe Olney in 1772 in Parrsboro, Cumberland Co., Nova Scotia. [their son] 1. Jesse Oman Lewis Jr. b. 1789, d. January 23, 1868."These oddities in dates can be a challenge to resolve, but can also be valuable clues in working out the next round of hypotheses and then with some diligence and a dab of good luck, verification or new data.
If Jesse's date of birth is accurate, it's possible, but unlikely, that he died at the age of 109. It's more unlikely that he married at the age of 12, and that he married in Parrsboro which didn't exist in 1772. The first known child's birth in 1789 coincides much better with a father who would have been 29 at the time, and begs another look at the marriage date.
