My grandfather was the Supr. of the German Protestant Orphan Asylum in New Orleans. It was located somewhere on Camp St. and took up a whole city block. His name was Gustave Pixberg and he come to the U.S.A. from Gremany. When researching my family, there were several children listed that were not my aunts or uncles. Maybe you can search his name thru Ancestry and try to put the puzzle together. I will be re-starting my search in the near future, so if you send me your email and the names you are looking for I will send you the information.
Best of Luck,
