Reagan

Reagan is an English surname that has been used as a given name, particularly for boys. It is believed to be derived from the Irish surname Ó Riagáin, meaning 'descendant of Riagán', where Riagán is a diminutive of the Irish word 'rí' meaning 'king'.

The name gained widespread popularity in the United States after Ronald Reagan, the 40th President of the United States, whose surname was originally a variant of the Irish name.

While the exact origin and meaning of the name Reagan are not entirely clear, it is often associated with concepts of royalty, leadership, and strength. In recent decades, it has become a popular choice for parents seeking a name with an air of authority and distinction.

Reagan is predominantly used as a masculine name, though it has also been occasionally used for girls, particularly in the United States.
