Hi, both appear in our family tree; my connection with them is indirect: my sister married a Klaus Heuer whose family is related to the Suppe/Rumland family.
My information is better for the Suppe family than for the Rumland family which only goes up one generation to Gottlieb Rumland, Clementine's father.
Please let me know where your information ended; maybe I can help.
