There are several different unrelated Irish families of which Lynch is the Anglicized form of including:
- Ó Loingsigh, meaning "descendant of Loingseach" (mariner), which was also Anglincized as Lynchy, Lynskey and Lindsey. Their chiefs were lords of the kingdom of Dál Riata in north-eastern Ulster during the 11th century.
- Mac Loingsigh – Clynch, Lynch, Mac Glinchy, MacClintock, McClinton
- Mac Loingseacháin – Lynchseanaun, Lynch
- de Lench, an Anglo-Norman name, which became ones of the Tribes of Galway. It is this wealthy landowning line that Patrick Lynch, who moved to Argentina, was from; one of his descendants was Che Guevara.
