Hi JW, I have not found Peter Jr. in the census before 1820 Overton, so really not sure how many sons he might have had. As to Wm. "Billy" mentioned before some researchers think he was not the son of Peter Jr. my information on him came from a gentleman in TX who is a descendant of Wm. I am not sure we will every find out the birth dates of our ancestors, unless someone should have their family bible with dates. Joel first shows 2 sons in 1810 so would assume Samuel & Larkin were born between 1800 and 1810. As for 2 Samuel's don't know of any other besides your Jacob Samuel who evidently went by his middle name. I do not know who Larkin married, like you have not found him after 1840 census. I had seen a reference to Mary Bookout before, but don't remember if it was marriage to Larkin. Which Joel are you referring to Joel Lucy son of Peter or another one? Joel Lucy that married Margaret Pennycuff stayed in Fentress and they are buried in Joel Lucy Reagan/Joel Hinds Cem. in Upper Crab Creek. The Anna you speak of is this a daughter of Larkin? Or the daughter of Wm. "Billy"? Pat
