Considering that by then more than 70% of the island was still natively speaking Welsh, and had no real reason to embrace English literature in their homes, we have to assume that there was an ex-patriot among the ranks here, and that appears to have been Mary. Possibly drawn to the island at the time through employment at the many military bases and factories built around the coastline, the majority of which no longer exist. Either way, to leave England in the mid 1900's to move to quiet pastures of Wales couldn't be branded as anything but an attempt at an escape from society. A risky one that Henry must have been worth the move for.
