I wanted to add to the research John has already done. I found a page of testimony for Pinchas Starczewski on Yad Vashem. It stated that he was born in Uniejow, Poland on 01/09/1928 and that he was killed in Auschwitz Camp in 1944. This was submitted by his brother YISRAEL STARCZEWSKI. I also found a page of testimony submitted by the same name for Bluma Bluma Starczewski nee Gdanski born 16/05/1897 and also killed in Auschwitz in 1944. There is also a page for Froim Starczewski born 1918 and Fajga Starczewski born 19/12/1925 and died 1944 in Auscwitz. Mindla Starczewski was the last submitted for Yisrael Starczewski and she was born in 1933 and she died in 1944 in Auschwitz.

If these are correct then they confirm who the family of Pinchas Starczewski were. Each testimony has a picture so it's quite interesting to see what they looked like.
