Dear Thomas, this is my oppinion: yes it is correct, in Germany they wrote my Reisen family in the 18th and 19th century also as Reihsen and in other documents as Reissen (they came from Gindorf to Kordel by marriage). Later on the writing was only Reisen. The hs in the name is today often seen as double s but it isn´t. The spelling was Reisen. Because the h in Germany is a "demotion h" and often used in names with double s (written as hs) to show up that the spelling is like a single s. The documents I do have of my Reisen family gove me the explanation to this kind of old german writing. Today it is unusual. When parts of my family emigrated to USA they believed in the old writing and brought the Reihsen name over the big atlantic ocean. I think this form of writing was unusual in USA in those times, but in german speacing areas in the states it wasn´t. They understood what it ment and so the family retained in the old name. On the other side the Name Crohs would be written today Groß or Kroß, c got unusual step by step after 1850 and changed to k, hs changed at the end of names to ß (ss) (Kroß, Groß, Croß) and in the middle of names to ss or s (Reissen, Reisen). Crofs can only be a misreading of Crohs, because of beeing unawared of this kind of writing. Werner
