I can't find any records regarding a marriage for Marion Scott, at least in Bermuda. I don't know what happened to Sam, sadly. The trail for Sam and my ancestor, Miss Scott, seems to end with the birth of their sons, Charles and Stuart Scott. I don't know what Sam's real surname was--he seems to have adopted "Scott" as his surname after the love affair with my ancestor, Miss Scott, and their children took "Scott" as their surname, as well. I wonder if Sam used another surname later? Judging by a photo of him, I'd say he looks about 50+, so he must have lived until at least 50. At any rate, I can't find anything about him anywhere. In fact, if my cousin hadn't told me about him, I wouldn't have known this story. I emailed him last night about Marion Scott. I'll let you know what he says.
Thank you for all of your help!
