[Richard Isaac ap Edward]

Hi there,
I'd like to know if the following people appear in the 1861 or 71 census of Llangadwaladr. They did appear in the 1941 and 51 census of that area.
ISAAC, Thomas b.1819, Gresford, Denbighshire
ISAAC, Margaret ISAAC  b.1810 not in county
ISAAC, Jane  b.1811 not in county
much obliged

This question should be in Denbighshire. No persons 1861/71 census fitting those ages +/- 2 years with search on Thegenealogist in either Montgomeryshire or Denbighshire. N.B. data bases are always being updated.
