    I have recently found some records for my g-g-grandmother Mary O'Brien who was born on the Muintevarra Peninsula in County Cork and immigrated as a child to NY by 1845. Her father was Humphrey O'Brien (b. about 1815) and mother was Ellen Sullivan. I will be traveling to the area in Ireland this April and I am hoping to learn as much as possible before I get there.  Does anyone have family from this area?

    Hello my name is Maria:  I am an American O'Brien. I have a family tree but have hit a wall with my 3rd Great Grandfather Thomas O'Brien born in Ireland in 1810 but came to America at some point and married a Sophia Thomas. He settled in Kentucky and died there.  There just seems to be a lot of Thomas O'Brien's born in Ireland around the same time and when I try to trace his passage over, there are a lot of the same named O'Brien's and the same year of birth.  If anyone can help I would really appreciate it.
