Just caught up with this on return from holiday. I hadn't heard of Yer Tiz, Whitecroft, but do know of Yer Tiz, Lydney, which is the name of a business run by Graham Sterry, a distant relative. www.yertizforestofdean.com Although plainly "Here it is" is a widely spoken phrase in Forestspeak, you never know if you ask Graham he might know of a connection to the Whitecroft house or some inspiration from it.
