In Chapter 5 of Charles Quest Ritsons' book Climbing Roses Of The World, a whole subchapter is dedicated to "The Work of Rudolph Geschwind" (page 54-61) Lots and lots of his crossings are described and in particular the ones with R. setigera are mentioned.
Yes, we have this excellent book listed as a reference for many Geschwind roses, though not with full text - an acquisition can only be recommended. The latest research on Geschwind is to be found in the Rosenjahrbuch 2011" in an very extensive article by Buchmann and Unmuth.
