Looking for any information concerning Rosa ?, wife of Joseph Back. Joseph and Rosa were married, probably in Marion County, around 1841 - 1842. Rosa was born in Kentucky around 1817. Dates and places of death and burial are not known. Their children were Jefferson (1843), Columbus (1845), Nicholas (1847), and John Robinson (1852). If anyone can find out Rosa's maiden name for me, I would greatly appreciate it.
