Thank you for the information, I will see if I can locate a copy of the book you mentiond (Art Bergeron's) in the library in the next town over. Our town is so small we have no library here. Possibly I can read an online version through the libraries remote access, which would be nice. Either way I will talk with our librian tomorrow to see if it is available.
Yes, my great grandfather did re-enlist as the gentleman recorded in his book. He apparently was ill for a time and discharged, then in his own words he "reinlisted 6 months thereafter under Col. Kelly". Which would support the two enlistments that the gentleman recorded.
Thank you for taking the time to reply to my query and sharing the information you had. I do not know much about my fathers family so any information is always appreciated.
Many thanks for your help,
