"Affection" is listed as No. 163 in "The New Sacred Star", MARSHALL, Leonard; Boston: Oliver DITSON & Co., 1865, in my Index listing.

I'm not going to dig it out tonight as most of the original books in my collection are quite fragile and raggedy, and I keep them in museum archival storage boxes, and try not to handle them very often. When I find a score I like, I scan/photocopy it and work from the copy in a 3-ring binder.

If you would like, however, I can pull the book and scan the score for you. I might point out, however, that it is not at all uncommon to find 3 or 4 (or more) of these old late-18th - mid 19th Century tunes which are quite different from each other, yet share the same title! It seems that Titles, melodies, and lyrics really didn't settle down and start living together regularly until around the time of the Civil War. Using the "Metrical System" mixing-and-matching tunes and lyrics was a common practice for nearly a Century. Another thing you will find is that an "alternative" melody for a certain song is actually just another harmony part for it; they swapped those around with gay abandon, too!

The study of American Music during this transitional period can get really interesting!
