In fact I do have one re Wolfe's Storming of Quebec. Supposedly Jeremiah Newberry (possibly age 15 or 18 at the time) was with Wolfe. Jeremiah was born probably 1743 in New London, CT (Barbour's records) and moved with his family to Westerly, Rhode Island. Is there a reliable way to confirm or refute this?
The best place to confirm the involvement of a French and Indian War participant from CT or RI is in the local county history.
For CT there are books originally published by the CT Historical Society from the records of the CT State Library. The one you are looking for is the two volume "Rolls of Connecticut Men in the French and Indian War, 1755 - 1764." The volume you really need is the second volume which covers 1758-1762. Heritage Books has this book for sale (the first volume is out of print, but should be back this year), so I looked for you and there is no mention of him in the index. I don't trust indexes, personally. It is also on Google Bookshelf as a limited view, but nothing appeared there.
For Rhode Island there is "Rhode Island in the Colonial Wars: A List of Rhode Island Soldiers & Sailors in the Old French and Indian War, 1755-1762" which I have never seen. According to World Cat the closest places to you where you can find it are the Library of Congress and the Thomas Balch Library in Leesburg, Virginia (one of my very favorite libraries, I used to be on the Friends of the Thomas Balch Library of about ten years or so (or at least it seemed that long)
Hope this helps.
