I have no connection to these people. I found this while doing other research and I don’t have any further information. This is from an old issue of the Rockland (Maine) Gazette dated June 14, 1860.
“CINCINNATI, June 7 – Henry Crawley, teacher in the Mount Auburn Female Seminary, while escorting two ladies home from the opera last night, was stabbed in the breast by some rowdies, causing instant death. The murderers have not been arrested.”
