Thomas and Sarah go back to his Welsh hometown Gethyn where judging from Sarah's age, she gives 29 to his mother, it is 1910 or 1911. Sarah in conversing with Thomas's mother, refers to Richard Bellamy, from the original Upstairs Downstairs, as Lord Bellamy. In the original Upstairs Downstairs Richard Bellamy was not elevated to the peerage until about 1917 just upon his remarriage to Virginia. By that time Sarah and Thomas had long departed the Upstairs Downstairs series. The Thomas & Sarah series only picks up the couples adventures right after they left Up/Down in 1910. So Sarah could not have known about Richard's Lordship as it was six or seven years in the future.
