I am really not sure what the deal is with Josiah. He was married to Mary Jane Lynn in 1849, but the 1860 Kanawha census lists (580)Mary J Bodkin with children Sarah 10, John 8, Cinthia 6, and Laura 2, living beside her parents (579)John and Patsy Linn. There's no mention of Josiah.
The 1870 Pendleton Co. census has a Josiah Bodkin 34, wife Leanah 36, William 14, Samuel 12, John 10, and Sally under age 1.
The 1880 Kanawha census on LDS has a Josiah Botkins 54, divorced, living with Andrew J. Botkins who I believe was his brother.
The 1910 Pendleton Co. census has a Josiah Bodkin 74, wife Hanna M. 54, stepdaughter Julia Bennet 12.
