Mr.
M'Call states that, for some time before his death in 1812, he held the living of Lambeg, the members of the French Church having by that time merged into union with the congregation of the Lisburn Cathedral.
A similar process took place in Dublin, Portarlington, and elsewhere, the descendants of the Huguenots becoming zealous members of the Established Church.
