Is anyone researching the Donnallans who resided in Calaveras County from 1849 to 1950s?My great grandfather homesteaded near San Andreas and mined with his brother in law, David Maloney.The mine is still called the Donnallan mine today.He had four children by Ellen Maloney: Mary Ann, Martin John, Ellen A., and Catherine. Mary Ann Donnallan married A.J. Huberty and Ellen A. Donnallan married John Nuner. I am trying to identify John Donnallan's parents in Dublin, Ireland. The family spelled the name DONNALLAN.
