Samuel and Agnis BRIMIDGER are my 6xGGP - through Christopher, Thomasin (or Tamzyn as she appears in some records I have seen, being an old Cornish name), then her son John MELHUISH (1795), William MELLISH (1823) (the surname starts corrupting), Emma MELLUISH (1856), Edgar Ernest WILLIAMS (1887) to my father and finally me.
Any help I can give or any information available will be gratefully received.
Stephen
