My ancestor WILLIAM MORGAN of Yorkley, Cole Miner, wrote his Last Will and Testament on the 24th August 1774 and it was proved on the 13th day of March 1775. He left to his wife Prudence Morgan "my share or moity in a cole work called Mendeland". Does anyone know where Mendeland is?

Sorry cant place this one - do you have the original ( or copy of) documnent or a transcription ?

< Mendeland in Africa is probably a little too far away !>

At the top of Dean Hill , near Littledean Hall, is a hamlet of Maidenham

I wonder if this is possibly the location, on the down side I'm not aware of a Gale in the area.....( only farming and springs)

There is a old mine about 1.5 miles north of this called Trow Ditch Drainage Adit in Mines of the Forest of Dean by Tony Oldham grid ref 6700 1530.
