Seamas is an Irish Gaelic male given name, derived from the Old Irish name Seamus, which means 'supplanter' or 'replacing'. It was initially anglicized as James, but has since regained its distinct identity in modern times. In Irish, it's pronounced as "shay-mas", with the stress on the first syllable. This name carries a rich cultural heritage and is often associated with Ireland's literary history, being borne by notable figures such as Seamus Heaney, the Nobel laureate poet.
"The name Seamas was used for five boys born each in 2003 and 2005, resulting in a total of ten babies named Seamas during those two years."
