Welcome to the great legend. From Dewey (pg 218) back to Thomas Edmond (pg188) in Jack Lilly's book LILLY FAMILY HISTORY 1566-1997 your line is there with dates, details, etc.

The great LILLY REUNION each year celebrates near the Robert & Fannie Lilly Monument where their original markers are at the base. Yes, they give Robert & Fannie 114 & 111 year life spans. 1696-1810 and 1696-1807. Which makes the children listed born when she was in her later years 70+. Is there a missing generation? -somethink so
but this is the way it has been handed down. Good luck. Vernon
