I am currently transcribing the nonconformist
microfilms for Norfolk held at the PRO. As you
are probably aware, the register book was
sometimes seen as the property of the minister
and sometimes ended up travelling with him. The
minister of the Kings Lynn, Broad Street
Independent Church seems to have taken the
register with him to Berkshire for a time before
returning to Kings Lynn. The entries from
the Church register baptisms 1745-1837 (PRO ref
RG4/2467) may be of interest to your members.
They include families with the surnames: Bishop,
Darval, Fowlder, Hardon, Harris, Leach, Lee,
Nibbs, Ranse, Searl, Sharp and Winch. Most of the
baptisms took place at Maidenhead.
