Etymology of LeidyWhat does the name Leidy mean? The Irish surname Leidy is an Anglicized form of the Gaelic "O'Lideadha." They claim descent from "Lidhda, a celebrated Munster chieftain of Dal-Cais, who fell at Clontarf in 1014. The exact situation of the O'Liddy patrimony in Co. Clare cannot now be ascertained; but it is believed that it formed part of the present barony of Tulla. In 1058, CarBerry O'Liddy, grandson of Lidha, founder of the name, and erenach of Emly, was slain; and in 1122, Conor O'Liddy successor of St. Ailbe or Emly, died. In 1171, say the Four Masters, a party of the O'Connors went on a predatory expedition into Thomond; they plundered Siartachain O'Liddy, and slew him in battle. " (O'Hart) Early Origins of the Leidy familyThe surname Leidy was first found in Cavan, where they held a family seat as a Dalcasian sept, chiefs in Thomond. 1 Irish history, after the Norman Conquest of England, was strongly influenced by the invasion of Strongbow in 1172, almost equal to the enormous Irish cultural impact on England Scotland, Wales and the whole of Europe before the Norman Conquest from the 1st to 7th centuries. Many Irish clanns, sept names were intermixed and family groupings became almost indistinguishable. This family name is descended from a celebrated Munster chieftain, Lidhda, who died fighting beside King Brian Boru in the Battle of Clontarf in 1014.
