It may be a coincidence, but there's a "Mr. P. Caspari" named as a guest of the 30th wedding anniversary party for Mr. & Mrs. Henry Flach in (T-Granville) Milwaukee. Other guests at the party were: Grosse Etzel Brahm Schwister Winkenwerder Gamm Loeb Trost Reinemann Webert Schulze Pancofe. There are both Caspari and Caspary entries or references in the index of the old German language press (I'm not a relative.)
"Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).
