Thanks for the Mary (Clazey) Walton Death Notice and the descendant count is something to think about! Husband Sergeant Joseph Walton d.1829 has a plain died at the barracks notice in the Courant and Courier.
The early part of this thread mentioned John Walton. Joseph's, possible, son John was a witness at Robert Walton's wedding Gosforth, 1823 i.e. Joseph and John were witnesses and I had John pencilled in as probable son/possibly uncle.

Looking for an Elizabeth Walton birth the LDS record throws a spanner in the works:
Register Newcastle upon Tyne St Andrew, Elizabeth Walton b.14 Sep 1811 & bap. 13 Oct 1811 but father John Walton, Allostock, Cheshire with mother Mary dau. of John Clazy, illegible 'Ayton', Berwickshire. John is not abbreviated. It is a transcript so could John be Joseph... or is this really John??
