Hi
Your message reads like she only married Thomas Dunn in 1861 when she would have been 70 but I suspect this is her in 1851 in Kingswinford
Samuel Dunn 34 b Somerset tin plate manufacturer
Ann Dunn 30 ?? Brecon Wales - not very clear on image
William Dunn 31 brother widower accountant b Bath
Samuel Dunn 5 nephew b Glamorgan
Mary Dunn 3 neice b Glamorgan
Sophia Dunn 60 mother b Bath
Mary Ann Waldman 26 servant
then moved to Wiveliscombe
There is no Sophia Dunn b Bath 1791 on the 1861 census. There is an Ann Sophia b Wiveliscombe 1809 and living in Exeter in 1861 but this cannot be the right one as she is shown as unmarried and is 20 years younger
