Manus, of Irish and Scottish origin, is an ancient yet lesser-known given name derived from the Latin 'manus', meaning 'hand'. It was popularized by early Christian missionaries who brought it to Ireland, where it has been used for centuries. The name Manus is often associated with Saint Patrick's patron saint, Saint Manchan, who was one of his earliest converts in Ireland.
The name Manus experienced significant fluctuations in popularity over the century, with a total of 125 babies named Manus being born between 1914 and 2006. The name's peak years were 1920, 1978, and 2004, each with 8 births, indicating brief periods of high popularity. Conversely, the name was least popular in the mid-20th century, with only a single-digit number of births per year from 1931 to 1973, and even fewer years (1946, 1950, 1963) with just five births each.
