I have the 1860 Indiana census from FTM. It has many errors, but can be helpful. I located a William W. Riggs age 21, Head of household, born in IN on page 0129 Jennings county. There was a Sarah Riggs age 64 b. NY (Insane) living with a Glenn family. Isaac N. Day, age 18, b. IN, page 244. Looks like his father was Charles age 73 b. CT. Wife Rachel b. NC age 53. Could be a second wife. Couldn't locate a Polk Day. Wonder if that was a nickname? Karen
