Tullis is a surname and boy’s name of Irish origin. It’s a variant of Tully, an anglicized form of several Irish surnames. These include Ó Maoltuile, meaning “devoted to the will”; Mac an Tuile, a variant of Ó Maoltuile; and Ó Taithligh. The latter means “descendant of Taithleach,” with Taithleach meaning “peaceful, quiet one.” It is also sometimes believed to derive from the Irish word tuile, meaning “flood.” If you have Tullises in your family tree, or are simply looking for a lesser-known Irish name for baby, Tullis could be the perfect choice!
