Germain m. Latin Germanus 'German'.

The name of a 4th C Spanish martyr, a 5th C French saint, a 5th C Breton saint, a 6th C French saint, a 7th C Swiss saint, an 8th C saint and patriarch of Constantinople.

In the 16th C, German and Jarman were used as anglicized forms of Gaelic Diarmaid (cf. Dermot), and thus some of the citations from England may reflect Irishmen immigrants.
