William Ramsey Mitchell, b ca 1819-21, in NY, lived in Lee, Polk Co, IA, where son William Alonzo was b in 1849. Unknown mother died at time of his birth. Older brother was Andrew, b ca 1842, NY. I believe William Ramsey Mitchell remarried ca 1850 to Rebecca Daley (Dailey), a widow with 3 children, and that they had another son, George F, b ca 1853. William and Rebecca may have been divorced prior to 1860 Census. I am looking for any information on William Ramsey, Andrew or George.
