Prefer not ot give out email address because of potential hackers, identity theft and spam.
There is an article on the Croit Roie Callows in the 1992 IOMFHS Journals but unfortunately it has a number of typo errors. Have up dated this article and could send you a copy if you you wish to give out your email address using "at" instead of "@".
The trick will be being trying to decide which of three James Callows or one Philip Callow (all first cousins), was the father of John Callow born 1825 Lonan. Apparently none of these candidates left wills or owned property.
