Irish Surname - Clark or Clarke
The name Clery / O'Clery, often anglicised to Clarke or Clark, is one of the oldest surnames in Ireland.
The surname is believed to derive from cleric, clerk, or scholar - one who can read and write. The Gaelic "Mac a' Chlerich/Cleireach", means son of the cleric or, sometimes, clerk. During the Middle Ages, a common pronunciation of 'er' was 'ar', so the man who kept the books might have been referred to as the 'clark'. At that time almost the only people who were able to read and write were members of religious orders and some of these minor orders were allowed to marry and have families. It was therefore natural that the term 'clark' or 'clerk' would come to be used of any literate man, particularly the professional secretary and the scholar.
One of the first native Gaelic O'Cleirigh clans were initially located in County Galway but soon dispersed to other parts of the country especially Counties Donegal and Dublin where the majority of descendants can still be found.
In 1890 Clarke was the 32nd most common surname in Ireland and there were approximately 15,400 people with this name. Counties in which this surname is most commonly found: Antrim, Cavan, Dublin, Louth and Mayo.
