Elizabeth mullan John mullan Belfast

Just wondering if anyone is aware of a John mullan and Lily or Elizabeth mullan that were married in Belfast , they went on to have lots of children however im unable to track her maiden name or find anything out about their marriage or life,i am thinking that John mullans father was Patrick mullan who had a sister called Elizabeth mullan and a brother called Peter mullan who seem to have grown up around the Tyrone area and also moved to the USA in the 1920s.i also know that Peter went on to have a child also called Peter who died in 1985,If anyone could be any help in finding more out about Elizabeth (Lily) or John mullan I’d really appreciate it thanks
