Protestation Returns of 1641–1642

The Protestation Returns of 1641–1642 are lists of English males over the age of 18 who took, or did not take, an oath of allegiance "to live and die for the true Protestant religion, the liberties and rights of subjects and the privilege of Parliaments." These lists were usually compiled by parish, or township, within hundred, or wapentake. They are of importance to local historians for estimating populations, to genealogists trying to find an ancestor immediately before the English Civil War and for scholars interested in surname distributions.
