Tirrany is of Irish origin, meaning 'from the grey fort'. It is derived from an old family surname that was originally used as a place name. The name Tirrany may have been brought to other parts of the world through immigration and has since gained international recognition. However, it remains relatively uncommon, contributing to its unique charm and appeal.
In 1992 alone, there were five newborns named Tirrany, with no additional births of that name in other years recorded.
