Shaunessy is a unique and distinctive given name of Irish origin. Derived from the Irish surname "Ó Seanáis", which translates to "descendant of John" or more literally, "son of John". The name has been historically associated with people of Irish descent but has since gained popularity worldwide as a unisex first name. It is often spelled variations such as Shaunessie, Shaunissey, or Shaunasi, but the most common spelling is Shaunessy. This name is not particularly popular, making it quite rare and uncommon, which can contribute to its unique appeal.
"Shaunessy was quite popular as a baby girl name in 1995 with five births that year, making up all the total recorded births."
