@ "General" It was the 12th century. The first Norman invasion was on May 1, 1169, the last was from 1200-1203 in the 13th century by William De Burch in Connauhgt. This was a sidenote about the origin of the name "Sean" as by the 13th century the dialects had been influnced strongly by the Norman influence.
