Thomas C Carroll was born on 7 Jul 1831 in Tipperary Co, IR. Margaret Blackburn was born on 6 Dec 1832 in Meath Co. IR. I am stumped and have a few questions.First - did they marry before or after coming to the US? Did he come first than she came or did they come together?When did they come?It seems that they went directly to Cincinnati OH where family members had already settled.Why did they move to VA where they had their first three children?When did they go and when did they return to Cincinnati where each died and was buried in the St. Aloyusis Cemetery, Bridgetown OH? Did he serve in the Civil War?How do I determine which Thomas C Carroll is which since there are so very, very many?This is the biggest problem. Is anyone related to this family and can you shed any light on the situation?Thanks.
