Library of Congress ; Raff ; making sense of things

After listening to those piano pieces by Kaspar, I find that they would make great background accompaniment to scenes from a Civil War documentary film.

Just to round out this thread, elsewhere here Eric reports his raising of this issue at IMSLP which has now produced the clinching evidence that the US Joseph Raff was definitely Joachim's brother Kaspar. It comes from a history of Owego NY which states "Prof. Raff was a native of Switzerland, a good violinist, but a better pianist. He was a brother of the eminent musical composer, Joachim Raff. He came to Owego in 1858. He removed to Binghamton in 1888 and died there July 13, 1893, aged 63 years." Very many thanks, Eric, for raising this conundrum in the first place and also for finding the solution.
