Boyce, William Edward - birthplace & family information wanted

I am searching for any information regarding my grandfather William Edward Boyce and his family in Ireland. I believe he was born in 1879 and came from Northern Ireland (possibly Belfast.....but I'm not sure of the exact location).  He emmigrated to Canada +/- 1900 and married there in 1917 to my grandmother Jessie Ross Williamson.  They had four children,  James, Mary, Margaret, and Hugh (my father).  He died in Canada in 1926.  Any help or suggestions for my search would be greatly appreciated.  I know very little about my Irish roots.
