Pleased to have gotten your response. The family names that you listed are carbon copies of the Cadogan's of Cape Clear.
My records go back as far as 1750 at which time the Patriarch of the Cadogan's was a Tiegue Cadogan who had 8 children...including sons Dan, Matthew, Timothy, Jerry, Michael and Denis....the extension of the family tree plunks all the way down from there to my daughter Bridget who is 2 years old and the youngest of my line.
A point of Interest, a Denis Cadogan of Cape married my grandfather's sister Mary Anne in 1868. Together they eventually owned a fleet of 3 masted trading schooners...the George Henry, Isallt and the Sarah Evans. My grandfather's name was John. His Brother Dan (Mary Anne's and my grandfather's brother) was the Captain of the George Henry and traded cargo to Newfoundland and Nova Scotia to the North and all the way to South Africa the other way in the late 1800's and up to the 1920's. There are Cadogan's of my line in Boston to this day.
Perhaps there are ships/port of entry records in Canada/Newfoundland/Nova Scotia that would have the ships named above listed.
I have records from 1750 primarily for my line...the others have never been filled in...perhaps we can help each other sort this out
I have been to Cape several times and was fortunate to meet a Denis Cadogan who was the son of Denis and Mary Anne..at that time in his 80's. He was a ship builder and sailor and to this day he and a partner own the sailing ship speed record from Fastnet Light House to the Falkland Islands acheived in the early 1900's
This is a pretty intelligent bunch...the first time I went to Cape with my father I was stunned at how many people looked like him...he had a unique color and complexion that no one else I have met in the US had. They would look you over from head to toe...speak a little Gaelic and then decide if you were "one of their own"..quite a test
