I am the great great grandson of John McKeone of Belturbet. He was born abt 1838-42. He was married to Mary McCauley and had three sons... Thomas, John and Charles. His father was also John. His mother was Margaret I believe. He had a sister Catherine who married a Thomas Plunkett. Can not find anything about John and Margaret. Trying to find out if John had any other siblings other than Catherine. Also Margaret's maiden name and if John had any siblings and parents name. Thank you for any help
