My ancestor was farrm bailiff at Glas-coed farm just north-west of Llansanffraid-ym-mechain when he died in 1870 (the outbuildings are now converted residences). Does anyone know who might have owned the farm so I can search for employment related documents?

Also his wife's death certificate lists her residence at death as 'Old Quarry' which I've found on an 1891 map near Glas-coed, but there don't seem to be any residences there. Any clues anyone?
