There is a marriage record for Frances to William Cartwright
Collection:England Marriages, 1538-1973
Marriage:Oct 2 1865 - St Edmund's, Dudley, Worcester, England
Wife:Fanny Miles
However Family Search https://www.familysearch.org/tree/person/details/LYCZ-VFV has Frances married to Samuel Banks in 1851 with 9 children born between 1852 and 1871, which is supported by census records in 1861 and 1871. In 1861 the census has the family in residing in Worcestershire but by 1871 they are in Featherstone, Yorkshire.
So I dont know how this correlates with marrying William Cartwright in Worcester in 1865? It seems unlikely that there were 2 x Frances / Fanny Miles one born in Shropshire in 1829 and the other nearby (about 25 miles / 40 km away) in Worcester in 1830 (although could still be the same year due to the imprecision of the record keeping) who both moved to Featherstone, although not impossible.,
Can anyone add any clarity? It may just be that 2 records have become conflated and now appear more similar than they should be?
Certainly these MyHeritage records make them appear to be the same...
