If you're Irish,come into the parlour.

Does anybody know,which part of ireland,Mary Molyneux came from?Perhaps someone 'out there' will have their marriage certificate.
I am really curious,as I am married for the last 45 yrs to an Ulsterman,I met in the Liverpool Y.M.C.A.
Also I am currently reading a bk about the Siege of 'Derry,or Londonderry,as I prefer to remember it.
In my ancestry,there's a Welsh element,two who lived within hailing distance,one being Susan Edwards,but I never thought there was an Irish connection.
Curiosity will get the better of me,and I will have to investigate,one way or t'other Beryl Moorehead
