I'm not a Falkenstein researcher; however, my WELLS genealogy provides some limited information on Paul and Albert Faulkenstine (born in Germany) enumerated in 1920 at the House of David in Benton, Berrien County, Michigan. See above link.
My father states that Paul and Albert were brothers and they ran the green houses on Hwy 12 not to far from Stewart School where my father went to school (about 1939-1946 era).
He states that Pauls daughter was Genie (Jeanie?)
My father's parents managed the House of David in the late 30's and early 40's.
