The baptismal register book for St Mary’s, Crathorne is held at the National Archive (Public Record Office) at Kew and covers the period 1777 to 1839.
During this time Parliament restored civil rights to Catholics in a series of Relief Acts beginning in 1778 and culminating in 1829 with the Catholic Emancipation Act.
The register begins with an introduction by Thomas Ferby:
“A Baptismal Book belonging Crathorne [sic] in which an account is kept of the children that have been baptized by me Thos Ferby Eng.h Miss. since Novr 1st 1777”
