There has always been a connection between the Gibney surname and the Sweeney family. I just don't know what the relationship was. Rose Gibney was a sponser at the baptism of Daniel Sweeney, Ballycomoyle, Castlepollard in Feb. 1880. Another Gibney, first name not known, was a sponser at the baptism of Catherine Sweeney on November 30, 1873 in Castlepollard. When my mother was baptised on August 15th of 1915 in New York an Anna Gibney was a sponsor. In 1854 there was a Luke Gibney who lived in the townland of Ballycomoyle, just a few acres away from where the Sweeney family lived. At the time of the 1901 census the Gibney family was no longer there.
