Christopher Healy or Haley

I believe my grandfather Christopher Healy was born in Nova Scotia around 1870. I can't find parents or siblings. He immigrated to the States. Married Kathleen Rose Gallagher. She was from Iowa. His family appears in the 1911 Canadian Census in Vancouver Canada. Not Sure if any of the children were born in Canada. Somewhere along the history he changed his name or took on the name of Haley
