Re: Mead family
I searched the Irish Family History online database at ROOTSIRELAND.IE. It has abt 20M B/M/D records for most Irish counties. Records before 1863 are increasingly sparse: almost non-existant before 1800.
For a Mary Mead and John Bee Marriage at any date, anywhere in Ireland, I found 0 records.
Note - Co. Kerry and parts of Co. Cork and Dublin City records are in a different database. Google Irishgenealogy.ie to reach it.
Hope this helps. Good luck.
