I've been looking at the parish registers for St Giles Cripplegate in the City of London for the late 17th and early 18th century. All of the baptisms and burials (but none of the marriages) have an initial next to them which is always either L or F. It starts in 1646 and stops in 1733. Can anyone suggest what this might mean?
It's too long a period for it to be the initial of the officiant, and I don't think there were any other chapels in the parish which this might represent. The parish did span the City boundary, so it could distinguish the inhabitants of the City from those who lived without, but if so, why L and F? I suspect it must mean something else. It doesn't coincide with when duty was charged on baptisms and burials. Any ideas?
