Lynch surname meaning

Lynch is commonly the anglicized Irish Ó Loingsigh, meaning “descendant of Loingseach.” Loingseach is traditionally connected with a mariner or exile, so “seafarer” is a useful gloss for the personal name, not a claim that every Lynch ancestor worked at sea. English and Scottish records can contain other routes to the spelling, and Irish families from different places could bear the same patronymic. O’Lynch and older Linche spellings show the record history. Parent’s name is the best-supported catalog type, with high confidence for the Irish route.
