Hey, My Great great grama was Mary Cavanaugh. I have pics and letters as wll as some hard-hat dining things which belonged to john Dodd.Pick up the book, SHIPWRECKS OF THE STRAITS OF MACKINAC, by Feltner, there is some mention of john Dodd in there. My Grandpa and Dad were bothh hard-hat divers out of Cheboygan. My Dad ended yp with john Dodds diving stuff. I have to think that the Dumans were the original hoarders.
