Searching for the parents of William Cathcart, born May 30, 1846 in Quebec, Canada (probably within the Eastern Townships). He migrated down to Cerro Gordo County, Iowa in the early 1870's where he married Annie Thompson (daughter of Watson E. Thompson) on April 12, 1873. They had two sons, John Watson and David William, before Annie died March 5, 1887. William later married Sarah E. Cummings and died in La Mesa, California on February 21, 1936.
I believe William's parents were originally from Ireland. Any information (or suggestions) would be greatly appreciated.
