My McGreevys lived in Manchester, England. Which census for which country have you looked at?
: We always thought my G,Grandfather, John McGreevy (b. circa 1872), was born in Ireland. I've recently seen census records where he lists his place of birth (and that of both his parents) as England. I'm sort of at a dead-end here (hopefully temporary). I don't know where or what records to search now to find his parents. If anyone could give me information or advice, I would be eternally grateful.
