i have been told by the genealogy ireland that the murphy family surname started by the dermot brothers grand sons of the last king of leinster
domhnall spainneach mac murrough caomhanach 1595 1632
his father criomthann mac murchadha mac murrough caomhanach 1557 to 1582
called the sea warrior,or sea wolf, viking name
after the last king of leinster died he had a very bad name so using the murrough name they cut it to murr and added a y,the very first murphy in ireland,
the wexford murphs are the direct descendants of the last king of leinster.
so all the murphy.s are from the last king of leinster,out of the population of 4 million 55 000 are murphy,they now spread all over ireland,
but if you were to keep your search in wexford dublin areas you should be able to trace your murphy family down from the las king of leinster,
