hello i know this is a long shot but could you do a lookup for sarah yeoman born around 1793 heddon on the wall in the 1851 census she was living in ponteland as a widow and a few neices and one nephew living with her if it helps they were jane hobson born 1821 thomas laws 1840 elisabeth fletcher 1827 and elisabeth fletcher born 1832 thankyou
The two Elizabeths and Edward are transcribed together but William and Sarah are above them and transcribed as Godman.
William Yeaman 55 yrs innkeeper born in county Sarah 45 yrs born in county Elizabeth Fletcher 14 yrs not born in county Elizabeth Fletcher 9 yrs not born in county Edward Wilkinson 68 yrs ag lab brn in county
this presumably helps with your query re William and Jane Fletcher and children- at least Elizabeth seems to be found.
Sarah Yeaman 68 yrs innkeeper b Heddon Jane Hobson niece 42 yrs dressmaker b Durham Chester Sarah Fletcher niece 25 yrs servant Thomas Laws 20 yrs joiner b Ponteland
on your other thread, Barbara found a WIlliam Fletcher and family which included a Sarah who would be this age.
