Looking for any connection for Percilla (or variation of the spelling) Hammerly Shepherd of Iowa - I'm thinking Japser/Marion/Keokuk county area, but I'm not positive. She married Daniel Joseph Cox before 1857, and they had three sons: Theodore Cicero b. 1857, James Wesley b. 1864, and Daniel Joseph b. 1870. I cannot find any reference to them in the 1860 or 1870 census, but the boys and their mother show up in Lucas County, Iowa in the 1880 census (Percilla's last name at that time is Rules).
Any information would be greatly appreciated!
