There he married Ellen (nee O'Dell) and moved to Traverse City, Michigan. Letters came from Dominic's family back in Ireland with the last name spelled "O'Dunne". It appears that Dominic shortened and Americanized his last name to Dunn. I have no knowledge of Dominic's parents names or siblings. His wife, Ellen, was widow with two children.
