He married German born Mary Stines. By 1820, maybe as early as 1810, they were in Marion Co WV/VA. They had 11 children, one of which was Samuel Jr (1820) who married Mary Vandergrift. I don't have a definitive source to connect Samuel Sr to Daniel but I'm somewhat confident of that Daniel is Samuel Sr's father, as I have seen in trees. As far as Daniel goes, I have a digital copy of a will of Francis Bice, m. Hannah Sterling/Starling, that shows Daniel as a son. My ancestor, 4X Great Grandfather, is Thomas Boice m. Edith Applegate, brother to Daniel. I can get you a couple pictures of pages from a book that gives the children of Samuel Sr, I believe those of Samuel Jr as well, and a little history that may lead you to more clues.
