Searching for any information regarding Hans H. Korner(1929-2002)His mother's name was Elisabeth Willer and his father's name was also Hans.There is a documentation of a Adolph Koerner as a doctor of obstetrics in MDCCCXXXV(1835?) and he possibly was a GGGGF or uncle.( The doctrine is in latin so it's hard to read.) Some information regarding the family history was compiled, dating back to the 1600's, but now has apparently been lost. We understand that we had some Prussion ancestors and possibly a French duke. Any information would be very appreciated.Thank you so much.
