The family home, Ysguborwen, seems to have been a fairly typical Welsh home. At first, only the Welsh language was spoken there. After all, it was the language of both of David's parents. However, Mrs. Thomas, like many Welsh parents before and since, realising that the language of the business world was English, engaged an English nurse to get her children used to speaking English. In 1859, the family moved from Calfaria Welsh Baptist Chapel to Carmel, the English Baptist Chapel opposite. English was becoming the language of the valleys, and the language of respectability. Accordingly, the upwardly mobile Thomases were going to be Anglo-Welsh.
