The townland where Mary Doonan was born was Stramatt. Here’s the household in 1901:
One odd thing to note is that according to the 1911 census Patrick & Bridget had 5 children of whom 4 were alive (all sons). That would suggest Mary had died. But people weren’t always totally accurate on census forms, and I can’t see a death for her in the area, so perhaps there were 5 children and another child that died.
Patrick & Bridget Maguire were married in Swanlinbar Chapel in Co. Cavan, on 28.7.1871. Fathers Francis & Patrick respectively, both dead:
Bridget was from Aughlish. You would need to search the baptism records for her birth c 1846.
There are two Maguire families in Aughlish in the 1901 census. I think that the family with Edward, Patrick & Ellie had a father named Charles (based on Patrick’s marriage certificate), and the family with Peter & Theresa had a father named Thomas, based on Teresa’s birth certificate.
Aughlish is in the parish of Cleenish. Their RC baptism records start in 1835. Stramatt is in the RC parish of Kinally. Their records also start in 1835.
The RC parish records are on-line free on the National Library site:
