This is another mystery in this family. Th Rhaesa appears in the letter list of the NY Sun Aug 1842 as a professor of music. Next in the unclaimed letter file of the Baltimore Sun Oct 1844. In 1845, June and Sept, he advertised his daguerreian gallery and as a music teacher in the St. Louis Reveille (MO).
He does not appear in any census or city directory that I have been able to find.
