Ruth Webb is a bit of a mystery. On the 1881 census she was recorded as being born in North Bradley, Wiltshire and in 1891 as born in Wiltshire. In 1901 as born in Rudge, Somerset and in 1911 as Somerset-born Mary Ann. North Bradley and Rudge parishes adjoin. She was the daughter of Samuel (labourer). There was a Mary Ann Webb registered in Westbury, Wiltshire R D which covered North Bradley in Dec 1848 which would fit, however she does not appear with Samuel on the 1851 census and I have not been able to find her yet on the 1851 ,1861 or 1871 censuses as either Ruth or Mary Ann
