Barry,
FWIW, Curiously the 'hanger' in Panshanger ..... is sort of "mis-spelt".
I suppose yonks ago folk were equally afflicted with poor spelling.
Look at how many letters and even august flying magazines manage to get it wrong. Spell check is a great introducer of such errors and surreptitiously too !

A hangar is a steep wooded slope, Panshanger is, and means, a large steep wooded slope. Historically the area was a large wooded slope on the southern side of the river Mimram valley. There are a number of places in the UK with hangar in the name. Spelling is correct.
