Hi - just when I thought I had run out of family to research, I came across your thread concerning Bianca K DeRoy Gotthainer.[b 13 Feb 1891 NYC, d. Aug 1963, FL]
I am looking into the family of my bother-in-law Ken Koplow. His grandfather,Robert Koplow [b. 1891 NY d. 1964 NJ] had a daughter Mildred [b. 1917 NJ d. Jan 2005 New Orleans]who married Harry DeRoy Jr. [b 1914 NJ d. 1996 Metaire, Louisiana]. Harry's parents were Harry DeRoy Sr. and Bianca Koch or Kroll.
Was her name Koch or Kroll? Her parents were?
Would appreciate any additional information.Would be glad to send what info I have presently.
