The only connection I can give you is that John Gale of White Bay was born at Bridport 25 Oct 1770. The west coast Gale's are associated with Symondsbury. Back then, Bridport and Symondsbury were villages about 2km apart. Today, Symondsbury is part of larger Bridport. There is speculation that John of White Bay and James of Codroy were sons of John and Mary (Dodge) Gale who were married in 1768 and who evemntually settled and died in western Newfoundland.
I have not seen it, but according to Kirk Butt, the will of Edward Gale, son of John and Mary and brother to James Gale, lists his parents origin and leaves bequests to his siblings. I do not think he left anything to a brother John. However, I am not sure sure if the siblings named in Edward's will comprise an all inclusive list of his siblings.
Also, In the early days of the Internet there was an article relating to the history of the Codroy area in which it was reported that in his old age James Gale went to White Bay to visit his older brother, John. I do not know why, but this statement was edited out of later versions of the same history. In my opinion, it appears too specific to be something that someone just made up.
My older notes indicate that James Gale was born c1776 in Bridport, but unfortunately I did not reference the source of this information.
