I just submitted a suggestion to edit the birth date. I thought I would explain my reasoning, and the submission form didn't allow me to do so.
The tombstone says he was 78 years 4 months when he died. This translates to March 1798. If there is a documented source for Nov 1795, that's great. I'd like to see it cited on this page, though, since it contradicts the tombstone. I recalculated the dates on my genealogy program and it came up with March 22, 1795. At Andrews death he was 78 years 4months 3 days old.
