thanks very much Donna. I think that closes off the possibility of getting any further unless someone has some other advice. I was hoping that this John Cubbon was the same John Cubbon who was born to Thomas Cubbon and Margaret Jick or Gick. my supposition from earlier IGI info was this potential ancestry of John Cubbon:

John Cubbon

Thos Cubbon = Margaret Jick
(born 1712?)

Thomas Cubbon born about Jan 1682, Malew
|
Thomas Cubbon = Marie Carter
born about 1655.
