Meaning of Blain

The name Blain derives from the Scottish Gaelic ‘Mac Gille Blááin’, which translates to ‘son of the servant of St. Bláán’. The saint’s name Bláán comes from the Old Irish word ‘blá’, meaning ‘thin’, ‘lean’, or ‘slender’.

Historical records show the name appearing in medieval Scottish documents related to the Clan MacLean, where it was sometimes used as a variant of Blaine.

During the medieval period, it was associated with the Clan MacLean through the ‘Mac Gille Blááin’ patronymic. While the name has Christian historical connections, it is not exclusively religious and has been used by families of various faiths, especially in Scottish diaspora communities in North America and Australia.
