I came across this post in a search for my own ancestors, the Bartlett/Adams families of Marldon.  This lineage also includes Salters, Bickfords and Jackson's.  I believe you will find the following link very useful.  Inside the link there is also an abbreviation guide to help along with understanding the contents & deciphering the language contained within. The link is a list of over 7500 Names files, researched and documented by Dr. Keith Matthews.  You'll be interested to find your James Jackson has a name file.  You'll also find files for 10/12 of the names you've listed at the bottom of your post. The Jacksons were early visitors to Newfoundland and perhaps even settled there, travelling back and forth from England with other Merchants and Mariners of the day.  I hope you enjoy these name files as much as I do.  They are fantastic!  Happy Researching!
