Bridget Doyle was born just prior to the first parish entries of St Peters Athlone, in Roscommon. I suspect the Jacob & Eliza Doyle who sponsored the baptism of her daughter Miriam Geraghty, on Nov 3, 1810, were her parents.
She probably married Michael Geraghty around 1809 and they baptized at least seven children at St Peters between 1810 and 1823.
