It is believed to have been brought to Ireland by Norsemen during the Viking Age. The name was later anglicized to Quinnell or Quinell. While it has not traditionally been used as a first name, in recent years there has been an increase in its usage, particularly among parents seeking distinctive and meaningful names for their children.
Quinnell is an unusual name with only five recorded births in the year 2009, suggesting it's quite uncommon.
