How come, that the father of Claus Ritter is currently according to Geni Andreas Ruthven from Scotland, but according to the "Frälsesläkter i Finland intill stora ofreden" ("Frälse" being an archaic Swedish term for nobility, "Stora ofreden" referring to the happenings in Finland during the Great Northern War, so translating to "Noble families in Finland until the Great Northern War) he was son to Johan Ritter from Bavaria?
