An Act was passed in 1703
"to prevent the further growth of popery" which made it obligatory on converts from Catholicism to Protestantism to provide proof of conformity. According to the Act a Protestant was a member of the Church of Ireland and not any other non Catholic religion. Source:
The Catholic Convert Rolls on the useful website from-ireland.net © of Dr. Jane Lyons of Dublin.
Although the Four Courts (Irish Public Records Office) fire in 1922 destroyed the Convert Rolls they had been calendared and recorded some time prior to that event (as were many other documents).
