Question:

What is the origin of the last name, Irwin?

Best Answer - Chosen by Asker: Irwin
This interesting surname is of Anglo-Saxon, Scottish and Irish origin. Firstly, it may originate from the Middle English personal name
Irwyn, Erwyn and Everwyn, from the old English pre 7th Century personal name "Eoforwine", composed of the elements "eofor" meaning
wild boar plus "wine" friend. "Eueruinus" (without surname) appears in the 1086 Domesday Book of Norfolk. The second source is Scottish
and is locational from Irvine in Strathclyde or from a Celtic river name, with the component elements being the Welsh "ir" or "yr" meaning
fresh or green plus "afon" water. The third source is Irish and is an Anglicized form of the Gaelic "O' hEireamhoin" meaning "descendant of
Eireamhan", a personal name of uncertain origin. One, Eustace Everwyn, appears in the 1310 Calendar of Letter Books, Devonshire. In
the modern idiom, the surname has many variant spellings including Everwin, Irwine, Irwing, Urwin, Irvine, Erwin, etc.. On October 7th
1565 Elene Orwin was christened at St. Margarets church, Westminster. Her father's name is recorded as Thomas Orwyn, so perhaps
"Elen" was the first in the new spelling form. On January 2nd 1680, Adam, son of James and Prudence Irwin, was christened at St.
Dunstan's, Stepney and John Irwin and Ellinor Harding were married at St. James Dukes Place, London. The first recorded spelling of
the family name is shown to be that of
Robert de Hierwyn (a witness), which was dated
1226, at Dumfriesshire, Scotland, during the reign of
King Alexander 11 of Scotland, 1214 - 1249.
