Hi, I was wondering if you ever found more information on Mr. Carroll? I am his great great granddaughter through his son Jake and have been searching for awhile for information. I think I found a marriage certificate for Sarah Gifford and John Carroll, but the image is very difficult to read. Her son Joe was born Jan 1879 and she was remarried in Nov. 1879. So my guess is he passed away sometime in 1878-79. I have not been able to find anything else.
