Wow that is quite a story. I have a Timothy b. 1824/25 in Cork, probably in Bantry to a son John and Catherine Kennedy Harrington. Timothy immigrated to US via NY and Cobh in 1849. He went by names Henry and Edward in some census'. He had a son named Edward in 1869. He also had sons named James and John. Are these names in your family?
Timothy Harrington born 1824/5 in probably Bantry, Ireland to (probably) John and Catherine Kennedy Harrington. Immigrated to NY in 1849. died in 1896. Was married to Ann (most likely Nancy Barret whom immigrated with him). Had children: John, James, Lavina, Catherine, Edward and Anna.
