Looking for Campbell of Ireland links. Have id back to a David Campbell b 3/27/1822 in Monaghan Ireland. Father was Thomas with no information and no mother listed. Know he had at least 2 sisters Mary and Martha. Married Eliza Jane Kirkpatrick (Johnston) 2/25/1847 and came to America 1854. Have good line from David to current but can not link back to actual Thomas father or unknown mother. On his wife's side I can connect to her father Dr James L Johnstone county Down, Ireland. Anyone have a similar Campbell trace going?
