Lewis of Telstra Nantyglo, Monmouthshire

[welsh girl]

Trostra was a farm where my great great grandfather Henry Lewis lived.He was born ?1798 and married to Rebecca ?.
I believe a large part of the farm was leased to the iron works .There is nothing on the site now.
Does anyone have any links with this family,they were also involved with leases for ebbw vale in particular the gantre estate.
