Rev. Rudolph Juengel was also a Lutheran minister. He was married to my father's sister (Gertrude Dohrmann). His sister, Thekla Malinda Juengel, was married to my father's brother (Rev. Edward Frederick Dohrmann). Edward was also a Lutheran minister (as was my father, Rev. Reinhold Dohrmann).
Thekla is still living. She has a twin sister, Irene.
