I am most interested in this "(Manx Slave Traders page 16)". I assume it is a book - could I have further details please? I am looking for information on a Captain Dickson (Dixon) who is mentioned in "History of the Liverpool Privateers and the letters of marque with an account of the Liverpool Slave Trade" by Gomer Williams, first edition in 1897 by William Heinemann and a second edition by Frank Cass in 1966.

I do know that he retired to the Isle of Man about 1840s from the following:-
"My maternal grandfather Captain Dickson was 79 when he died having been at sea 50 years. At 20 he commanded a ship and was mostly in the African trade and did a good deal in the slave trade when that traffic was lawful he was lame from a bullet in his knee got while beating off a French privateer he being then in command of a Letter of Marque. In his old age which he passed in the Isle of Man he became very religious."

I do not know where or whether he was a Manxman before he retired.
