I also have a copy of Shep Fearon's History of the Fearons Trading in China, given to me recently by his nephew Daniel Fearon. I am more interested in the Fearons of Gilcrux and some of the family tree given by Shep of that branch is, I'm afraid, wrong. At present I haven't worked out the connection between the Dean Fearons and the Gilcrux Fearons, or for that matter, the Lorton and Whitehaven branches. It is I think a little fanciful to relate them back to the Ferrers from Devon but? One of my Fearon relatives also lent me a copy of Shep's pamphlet - she is the widow of George Fearon of the Margoliouth branch of the family. They must have known Shep. Grizel Baird seems to have done quite a bit of work on the Fearons but I don't know where her stuff is nor where Shep Fearon's papers are. His military papers are in Kings College, London, Library.
I think I have got my Fearons back to about 1700 but will need to look further into the records in Carlisle, particularly of the Valentine Dykes who appear to be the local landlords.
I am also trying to find out more about my great -uncle Captain Carter Fearon who was one of the last, great sailing ship masters.
In Sheps pamphlet mention is made of a Daniel Robert Fearon who wrote a short book called "School Inspections". He was also brought to my attention by a friend who was the former Dean of Education at the University of Ulster and who was interested in C19th Education and who had come across him as one of the Assistant Commissioners for the Taunton Commission, along with Matthew Arnold.There is some of his writings in the library of the Institute of Education in London.
Another academical friend told me about a memorial stone to a John Paul Fearon of Middlesex in a church yard on the Isle of Wight
More information on either of these branches would be useful
