What is "peadar"

Peadar is a masculine given name in the Irish, and Scottish Gaelic languages (in Manx Gaelic orthography the same name is rendered "Peddyr"). The names are ultimately derived from the Greek word petros, meaning "stone", "rock". The Scottish Gaelic Peadar is said to be reserved for the saint, and the Scottish Gaelic Pàdraig. It is a variation of the name Peter.
