Joseph was reportedly born 1778 in MD. He was found on 1810 census in Christian County, KY with wife Elizabeth Hargis and severalchildren. He next turns up in Gallatin County, IL where Elizabeth dies and Joseph takes on a new wife, Mary Mussett and son, Wm from previous marriage, From there, the family moves to Waterford , Fulton Co, IL where they both live til death.
In particular, I am looking for info regarding this man's birth parents and sibs. One brother might be William Cozad/Cozart who was also in Christian County KY in 1810. He married Mary (Polly) Ruff (Roof) there in 1802. They then moved to Hardin County, KY where Will died a few years later.
All responses are most welcome and appreciated.
