There are a few more children for Wm Cubbon/Kath Gellin(g)

Another Kath 1771
Ann 1773
Thomas 1778

There is no burial info for a Cath or Kath--maybe the same child was ch twice??
The only burial for a Marg in the time frame is
Marg child of William May 13th 1789

I read the will of John Gelling/Catherine Killey and am totally confused as to who their children are??
