I'm afraid I haven't followed up the Cretney side of the family, and I can't remember where I got the figure of 14 children from, probably collected orally some years ago.

The children of John and Eliza Callister were:

Eliza Anne Ch 5 June 1865.
Married Jack Corlett at Ramsey, ~1904. She died in 1948.

They are probably buried at Marown. John in 1936, and Emily in 1943.
