Sinnott
Sinnott is a surname of Anglo-Norman origin, derived from the personal name ''Sigenoth'', meaning "victory" (''sige'') and ''boldness'' (''nōth'') in Old English. The name was brought to Ireland during the Norman invasion in the 12th century and became strongly associated with
County Wexford, where the Sinnott family established themselves as prominent landowners. Over time, the name evolved into several variants, including
Synnott,
Sinnett, and
Sennett. Today, Sinnott remains a distinctly Irish surname, despite its Anglo-Norman roots, and is found among Irish diaspora communities worldwide.
