My great-great-grandpa, Aleksander Danielewicz, was born in about 1850 somewhere in "Kresy Wschodnie" and then he ended up in the Boduen orphanage in Warsaw. I think there was also a mix up between two different ways of spelling his last name: Danilewicz or Danielewicz. My family is Danielewicz. We don't know anything else about his ancestors. Can anybody help?
