I've been looking myself. My dad says that was his grand uncle but family history gets hazy.What he tells us is this: His mother was Zdenka Svaboda, came from Czechoslovakia as young girl around 1906. Sister Mary came as well. Sanders may be another name in the family.My grandfather also came as a young boy near turn of the century. Anthony Francis Von Kluck. Both sides settled in NYC area and supposedly kept little touch back home but supposedly were Czech, not German.My dad recalls his grandfather being grandmarshall of Czech/Slovak parade in NYC.Around WW1 when German sabatuers exploded munitions depot in NJ family supposedly changed "u" to "i" fearing anti German sentiment although never a legal change. He also believes many family members in Czech republic lost during WWII.Other than that only relatives we knew state side were a cousin Paul in FL and Dorothy in CT.I searched Ellis Island site and could find nothing.So I know virtually nothing about old country except they spoke Czech, not German around the house.Any of this of use?
