Lutheran
Lutherans is the plural of Lutheran.
A Lutheran is a member of the Lutheran Church which seems to have followed the ideas of Martin Luther who was born in about 1483.
A group of Lutherans were massacred by Spanish Roman Catholic Church soldiers in 1565 near the River of May near Jacksonville Florida. The Catholics killed the Lutherans because they were not Catholic and therefore heretics. (See MPD_0015 for more information.)
