The name was taken early to Ireland by settlers in the Pale, the progenitors of the Sherlock families in Ireland, came over from England, and had established themselves in County Kildare, by the 14th century. The parish of Sherlockstown and the townland of the same name in the barony of North Nass, County Kildare, mark their principle place of settlement where their seat was Sherlockstown Castle. The name is now found principally in the capital, but also in County Meath, and scattered in other counties.The associated coat of arms is recorded in Sir Bernard Burkes General Armory. Ulster King of Arms in 1884. Ireland is one of the earliest sources of the development of patronymic names in northern Europe. Irish Clan or bynames can be traced back to the 4th century B.C. and Mac (son of) and O (grandson or ancestor of) evolved from this base, the original literal meaning of which has been lost due to the absence of written records and linguistic ambivalences which subtly but inexorably became adopted through usage. Genealogists and lexographers accept that the patronymic base does not refer to a location, quite the contrary. The use of the prefix 'Bally' (town of) attaching to the base name, identifying the location. The base root was also adopted by people residing in the demographic area without a common ancestor. These groups called 'Septs' were specially prevalent in Ireland. The first Normans arrived in Ireland in the 12th and 13th centuries to form an alliance with the King of Leinster. Under Elizabeth I in the 16th century, settlers from England established themselves around Dublin, then under English control and Presbyterian Scots emigrated to Ulster, introducing English and Scottish roots.
