They have to fit together somehow. Charles Lyman ends up in Colorado. I keep plugging away at researching the multiple Charles Sleades in southern Indiana--of which I am a descendant of one. Too many Charles Sleades to not be related somehow. I hope to figure this out. Keep me posted if you find something! I would love to solve this mystery!
"Sleade" also comes up as a Welsh word that refers to a sled used in the salt marshes. I am so glad to hear that someone else is working on this!
