Moving on, there were only two baptisms I found which looked like the children of James Corkill & 2nd wife Catherine [possibly Curlett] now know CROW, first wife having died 1744:

Robert s/o James Corkill/ Catherine bapt Parish Church 25 Dec 1745 married Jane.
Edward s/o James Corkill/ bapt Parish Church 20 Mar 1747/48.
The others were:
James d.1828 marr. Bahee Lawson d.1815 [will], 6 children baptised.
John marr. Ann Kissag 1765, d.1821
Isable (married TEAR)
…… (married QUAY)

The children/grandchildren of James & Catherine in her 1784 will:
Grand son William Corkill son of John Corkill Ballinsloe
Son John Corkill (her execr)
Son James Corkill
Son Edward Corkill
Catherine Quay her granddaughter
Her grand Daughter Rob’t Corkills Daughter
Her Daughter Isable Tear

I don't think they were defrauding Edward by getting John to take over the land and the large debt, as Robert was the eldest and had at least one child. John could have been the youngest, being her execr., if the others had already received support. The illeg John is an interesting thought, except that James was probably married to his first wife in 1739 - very risky if he planned to have children with her, and land was involved?
A Jon CROW (infant) was buried Dec 27 1740.
