Thank you Mary, I had seen it but discounted it, Elizabeth Fletcher ( nee Wall) born 1820 is with Thomas Longden in the 1851 census in Sandiacre.
they have William 10yrs, Ann 6yrs, Maria 4yrs, Hannah 2yrs and Ruth 1 month. All under the name of Longdon.
But it's only when you follow Elizabeth /Eliza Wall through her marriage to Samuel in 1836, the census returns and the births of her later children, that you can see where she is in the country, it took some while to find her as a Longden, and confirmed it through plotting her eldest son's progress through the census returns. I believe Eliza was Thomas Longden's common-law-wife, as there is no trace of a marriage between them under any of her names.
The child Ann 6yrs, has her mother as Eliza Longdon formally Fletcher on her birth certificate in Dec q 1844, this is her first child with Thomas, the other children's birth certificates say Eliza Longden, formally Wall.
She is named in her father's will as Eliza Longden in 1856.
William's surnames change over the census years between William Longdon, William Fletcher and William Longden- Fletcher.
I really am gratefull for the help you give and the time you take to search on my behalf, I usually can find a way through a family mystery, but it is getting me at me, because I think, they have to be there...........
