We can document Joseph Cavin's marriage to Hannah Keele and to Mary Keele. Both of their tombstones in Polk Co, MO say that they were the wives of Joseph Cavin. Polly Keele, his first wife, died probably in Bedford Co, TN, and there is no record left of her grave.
We have also found the marriage record for his fourth wife. MRS. Margaret (Abel) Wollard, widow of Nathanial Wollard of Dallas Co, MO on December 17, 1872, Dallas Co, MO.
