Hello again. I wondered if this was of interest. In 1920 Francis "Frank" Coltart died in Duns, Berwickshire. In some of the censuses he states that he was born in Troqueer, Kirkcudbrightshire. His DC states that he was the reputed son of John Coltart, General Labourer and Mary-Lilias Gray, afterwards married to Thomas McMurdoch (sic), Coal Miner. His wife was Margaret Drummond. The 1851 census shows a Thomas McMurdo, miner, at Craigdarroch, Sanquhar, with Lilias his wife and their children Margaret, 2, John, 5 mo, and Francis Little, 5, stepson, born Troqueer. I hope this helps. Maxine.
