I developed an interest in Ireland when I was young. One of the
reason was that I found out I had some Irish background. My grandma
on my dad's side was a Reid, which is an Irish name. The following
is information on this surname and its history.
"In addition, a number of Scots Gaelic surnames - MacRory, Ruaidh ("red"), and MacInroy - were frequently anglicised Reid, and many Reids in Ulster especially are descended from Scottish settlers. However, there were also two Gaelic families, the Ó Maoildeirg ("Mulderrig" - "red chieftain") of Mayo and Antrim, and the Ó Maoilbhrighde ("Mulreedy" - "devotee of St. Brigid") of Co. Roscommon whose surnames have often been anglicised Reid, by semi-translation and abbreviation respectively.
"Nano Reid (1905-1981) was one of the best known Irish painters of her generation, celebrated for her skilful evocation of the landscape of her native Co. Louth."
