Don't have any info on Joseph but the following (if you don't have it already) is from the Jackson County WPA list Page 265: Wilson, Theodate W. Nims ( Mrs Joseph Wilson) 1841 to 1-19-1879; Mt.Hope cem. lot 49-523, Maquoketa Wilson, Thos J. 1843 to 11-10-1910; Mt Hope cem. lot 1229; Maquoketa Co. I 12th Ia.inf. There are NIMS family members listed on Page 170 also buried in lot 49-253. Did your Joseph remarry after Theodate died in 1879? Their marriage is recorded in Ellis 1910 history on Page 680: Joseph Wilson to Theodate Nims, May 3, 1870, by W. B. Whitley, justice of the peace. Hope this is of some value to you. Duane L.
