Some churches are always open in daylight hours.
Others are locked for fear of vandals. It may be
possible to borrow the key from a '"steward " nearby.
ONLY in one or two churches that I visit is a map/plan
provided inside the church but no one will be on
duty. Even if time allowed you would need to buy
an armful of indexes. Some people on this board can
do "look ups " OR you will need to visit MNH library/
free access to indexes.
