I wish to correct my previous posting. According to the 1841 census I now believe that Sarah Fairless was born in 1811. She was married to Thomas Thompson about 1835 and their first child was Elizabeth, then Jane, followed by John. Their place of abode seems to have been near Whitwell Colliery in the parish of Sherbourne, east of Durham City. If anyone can give me further information about Sarah Thompson ( nee Fairless?) it would be a great help.
