My great grandfather was James Behan (b. 1873). Although in my family research this appears to be the last use of the name Behan as all future lines are recorded as Bahan. My mother was born Margaret Bahan in 1927, the eldest of six children). Her parents were Thomas Bahan (b. 1902) and Anastasia Brennan (b. 1903). My mother's grandfather was James Behan who married Margaret Ann McCabe. I cannot trace any further back to their Irish roots - Can anyone assist me and be prepared to exchange any information?
