Hi. I am Lamiel's brother, Harry. Arthur Oesterreicher was born to Kate Feldmar who lived at #5 Widerhofergasse in Austria in the late 1930s. I have no information where his father, Jacques Oesterreicher, was born. However, I am in possession of documents, possibly birth certificates, scripted in german and sealed with sealing wax, dated in the late 1800s. Perhaps these documents could be translated to provide additional genealogical information.
