Merski,
This is an interesting couple, I thought Timothy was possibly married to a Bridget that died in 1850. I suspected this because a Mary Donahue was born on or about Jan 3rd 1847, Mary's mother's name was listed as Bridget but the father's name was blank. This lack of a father's name occurs in the records when the father is not alive. I took it to mean Mary was born after the death of her father, and Timothy seemed to be the only Donahue male to die within 9 months of Mary's birth. So, I kinda figured (wrongly?). Any luck with cross referencing your stuff with mine? worcirish
