My research on McNicholas family roots has identified connections to the following Mayo families: Byrne, Jordan, Lavelle, Kilgallen, Lyons, Murtagh, O'Horo, Roach, Sherlock and McGuire. I would be interested in talking with any one who has parallel interests. My time frame is 1750 to 1900. My geographic focus is the parish of Bohola in the Poor Law Union of Swinford with some dispersion to adjacent areas. John P. McNicholas Vienna, Virginia
