Thomas Doyle : Short Biography

Looking for information on Thomas and Mary Doyle, Parish Davidstown.

Thomas was married to Mary (Mary A), unknown maiden name. They had three children: Mary A born 1847, Bridget born 1949 and Frank born 1852. Mary and Frank emigrated to American early 1880s, we believe Bridget stayed in Ireland. We are sure that Thomas and Mary were in Parish Davidstown based on the obituary information published on Mary A Doyle, my Great Aunt, who died in 1922. Based on their children's birth dates this would mean they would have minimally spent some time there around the mid-1850s. We don't have any birth or death information on Thomas and Mary Doyle so any leads would be greatly appreciated. Thanks so much. Mary
