St.Martins/Whittington/Oswestry 1841-1851

[FRANK DAVIES]

With a great deal of help from Rootschat members things are now coming together
BUT
I have william+Harriet Davies with children
Joseph/susannah/Mary on the 1861 census at cefn bychan.
But son Samuel is missing on this Census (age 12)

On the 1901 census i have Harriet (age78) and Daughter Sarah Griffiths (widow )  age 53 at Heol Maelor.

Where was Samuel in 1861(My g.grandfather)
and where was sarah in 1861 age 13.?
I have proof that samuel and sarah are sisters but I need to confirm it on the 1851 census
The family are originally from St.Martins Whittington oswestry.

Thanks FRANK
