Joseph C. and Frankey should have been divorced before his second marriage to Mary Artrip on April 7, 1887 in Dickenson, Virginia.
If that assumption is correct then why were three children born to his first wife Frankey after his second marriage?
The ages are correct according to the 1900 Pike, Kentucky census in which Frankey Kerr is listed as divorced with N.E. born aug 1888, M.A. born oct 1889 and P.J. born aug 1892 Al in Kentucky. (Pike Co. probably since Francis was with Joseph C. on 1880 Pike, Kentucky census as well as 1900)
Apparently Joseph Crockett may have been visiting more than just the kids? We do know for a fact that Abner would travel back to Kentucky on a horse by himself while blind. So for Joseph it wouldn't have been as hard as that and I am sure he would have visited his other children.
The only other solution is Frances and Mary's husbands were two different men. But I was able to prove they are the same man as follows:
Name Joseph C. on 1880 Pike, Kentucky census with Frances, John G., Mary A., and Roxy C.
Name J.C. on 1900 Dickenson, Virginia census with Mary, James A., Hy W., Nelson, Frank, Fred, Charley.
Name J.C. on marriage record to Mary Artrip, parents listed as Abner and Mary Jane Kerr; place of Census for J.C. listed as Pike, Kentucky; listed as Divorced.
Mary Pop Artrip's lineage listed husband as Crockett as per family tradition.
Abner R. and Mary J. Kerr on 1860 Buchanan, Virginia census with son Joseph, born 1855.
A.R. and Mary J. Kerr on 1870 Buchanan, Virginia census with son Joseph C., born 1855.
