I'm not sure this is the family you are seeking. Their is a family tree on Ancestry.com which cites The Genealogy of the Wolf family as its source. Link: http://contentdm.lib.byu.edu/cdm4/document.php?CISOROOT=/FH29&CISOPTR=25394&CISOSHOW=25392
I am unable to access the file. It does list the following on the tree: Hans Emil Rhode b 4 May 1895 Darmstadt, Hessen d 1 Apr 1958 Griescheim, Darmstadt- Dieburg, Hessen
Wife: Maria Gotz 1893-1981 (married 1918)
Son: Martin Rhode 1922-1945
Son: Private
