Thank you for getting in touch. I know nothing about Marden, still less about New House, although I must have passed very near it quite often when going to Wales from Oxford where I live. I knew there was a Hereford connection in the family, but it wasn't till recently, when I began researching my family history, that I discovered that a great grandmother came from Marden, was called Mary Adams and was the daughter of one John Adams. He described himself in the 1851 census as 'guardian and farmer of 280 acres employing 9 labourers'. I'm not sure that I'm brave enough to ring the Adams family who currently live nearby, but I might write to them. Thank you for telling me about them anyway. I shall certainly make a detour to Marden next time I go to Wales.
Kind regards,
Gisele.
