The Marches are the borderlands between England and Wales

I believe this originates from an old Anglo-Saxon word, 'Mearc' meaning boundary or something like that (off the top of my head)

So the Hereford 'marches' would be the west side of the county of Herefordshire that borders Wales

It isn't really referred to as the Hereford Marches though, more commonly as the Welsh Marches but i guess this term would narrow it down to those areas in Herefordshire.

R. Millward has written:

'The Peak District'

'The upper Trent'

'Public expenditure economics'

'The Welsh Marches'

You can use marches as a noun or as verb. An example of marches as a verb would be "He marches like a chicken" An example of marches as a noun would be "All marches begin with a single step"

The proud and noble Welsh surname of Baylis derives from the Old French language word meaning bailiff. In Wales, this occupation would have been an agent for the English lords of the marches.

James of the Marches died in 1476.
