Just to keep you updated on the search of March Hywel and the surrounding areas. I took your advice and researched further into the history of Cilfrew and to the farms up the valley. Some amazing history came to light, most of which i never knew, especially to the battles up through the valley, and to the possible Roman way over March Hywel through to Ystradgynlais.
I have however had to find out if any "scheduled" archaeological investigations where on for the near future, and as far as i know none are.
Sunday will be our first full grid search of the area, which is ironic really as it will be four years on Saint David,s day when we scattered my fathers ashes in the area lol, hopefully he will pull some strings for us in  divine intervention.

The weather has made it impossible to get to this area, however my youngest son and I have searched the lower areas closer to Cilfrew, which has turned up pre decimal coins, nothing spectacular from florins, farthings and old pennies, which at least proves that the land was being regularly used over 150 years ago.

Hopefully I will be able to furnish you and your colleagues with something of interest along with photographs for your reference in the near future.
You could go as far to say this is literally the land of my father.
Well done again on your site, which is proving a great interest to many people.
