Good grief! It seems Terry MacSwiney has more descendants than Genghis Khan. Terence MacSwiney, the martyr, commander of Cork No.1 Brigade and Lord Mayor of Cork was married to Muriel Murphy, of the Murphy brewing family in Cork. They had a daughter Maire, who returned to Ireland from Germany and was made a ward of court in 1932. She married Ruari Brugha, the son of Terence MacSwiney's close friend and comrade in arms, Cathal Brugha, becoming known as Marie MacSwiney-Brugha. Muriel MacSwiney became involved with a French intellectual had another daughter Alix). Maire and Ruari had at least one daughter (who would be MacSwiney's granddaughter) and if you are descended from the children of Maire and Ruari you should be able to give the pedigree clearly and unambiguously.
