I was very interested to read your message, particularly as two of the people you mention are some of the family members I know least about:

I had Agnes married to William Cannell of Liverpool -

Agnes Corjeag m. William Cannell Sep qtr 1879 West Derby 8b 639

did she subsequently marry someone named Walker?

Also, from Frances' Manx Notebook I had the following:

[From Brown's Directory, 1894]
List of Manx People in Kimberley [at time of Boer War 11 October 1899 to 31 May 1902]
Mrs Albert MOSS, daughter of Mr. W.H. Corjeag, Kirk Michael

which I guessed to be Catherine, daughter of William Henry Corjeag of Mill Bank.

I would love to find out more about both these women if you are willing to share. I am descended from Richard Corjeag (1739-1795) youngest son of John Corjeag & Christian Boddaugh of Ballalonna, through a line that went from Kirk Michael to farm at Jurby and Ballaugh, gradually changing their name to Cavendish and ending up in Douglas.
