I can find his marriage to Margaret on 11/14/1848 on Geneanet and am looking for more info on other sources, currently military records. Do you know what town he was born in in Northern Ireland? Antrim? Londonderry? I can find discharge papers for William Taylors, and there may be death or burial records in here, but a DOB or POB would help narrow the search, if you have it. Thanks. Oh, William Taylor's father's name was James and Margaret McCaul's father's name was Charles, if you don't already have this information.
