Boyce, William Edward - birthplace & family information wanted

I am searching for any information about my grandfather William Edward Boyce. I think his birthdate was appoximately 1879 (not sure, may be later). I believe he was from the area around Belfast, Ireland (county Antrim, province Ulster).  He emigrated to Canada around 1900.  He married my grandmother Jessie Ross Williamson on 16/05/1917 and lived in Winnipeg, Manitoba, Canada. He had four children.  He died on 02/10/1926 in or just outside Winnipeg, Manitoba, Canada. I would like to find out his actual birthplace and any other information about his family in Ireland.  Thank-you.
