I have knowledge of Josiah's son Michael.He was the son of Josiah and Mary.Michael Bartlett moved to IL bef. 1836 at least.He had settled in Davenport, Scott Co., IA and across the river in Moline and Hampton Twp., IL. Two of Micheal's children from his marriage to Bethina Babbitt married two of my Great Grandfathers siblings.Have other information on them, Michael was born in 1790 in VT. Bethina was bn abt. 1814 in OH.He was first married to Zerviah Edwards, she died bef. 1833.
