As you who have Irish ancestors know it's a tough search through church records...
My grt x 4 grandfather was John Duffy = to john smith in England for sure!
He was born around Tomboholla Co Mayo which due to boundary move was under Tuam Co Galway these days. His children were all born in Aughamore Co Mayo but his brother Martin was baptised in archdiocese of Tuam at a place called Bekan Co Mayo which is near Knock.
Their father was Martin Duffy & Mother Brigit Lyons both late 1700's but it's John's wife Harriet (not a particular Irish name) who's surname I need
John Duffy 1801
Harriet ? 1805
Their first child born about 1833 so their marriage would have been from about 1825
Help am 15 years at a brick wall with this search
