these are the only Catholic priest names that I can see that look anything like 'Wicklamee' - neither are Matthew though ..
1870 - ROMAN CATHOLIC CHAPELS:
Dunlavin. .(Wicklow)
Rev James Whittle, parish priest; Rev Terence O'Reilly,curate
Gorey...
Rev James Lacy, P.P.: Rev Robert Sinnot and Rev. James Woddick, curates
it might be worth checking out for clues to the witnesses - I've seen post relating to the Mythen surname in Wexford that could be a clue..
