Manogues from Canada/Ireland

My granfather, Albert Manogue came to San Francisco from Canada, around 1900. He had siblings, but was raised by a step mother. I will look at the papers and find more information. I believe his family came from Ireland. When I was very young, the 1960s, a cousin of his, Monsignor Manogue, of Ireland, would come to visit. But he died many years ago, and I'm not sure where in Ireland he was from.
I'll do some research. A.J. Manogue tookmany pictures and left paperwork
