kantor family from Warsaw and Jasionowka(Brustyn)

I am looking for anyone who could be related to the following:
Aron Kanowicz-Kantor family of Warsaw, Poland who died in Warsaw Ghetto in WWII along with his daughters. Kantor family who came from village of Jasionowka. One brother changed his family name to Brustyn-family now living in Israel. Some of Brustyn famliy immigrated to USA and changed name back to Kantor or Cantor-Possibly Haim David or Bezalel were first names. Also daughters of Brustyn immigrated to USA. I would like to find these Brustyn-Kantors whose children and grandchildren now live in USA.
Two Kantor brothers, sons of Aron Kanowicz,immigrated to USA. In Poland their family name was Kanowicz, changed to Julius Kantor and to Hyman(Herman) Cantor. Lived in New York area or Detroit. Aron Kanowicz was father of Julius and Hyman. His daughters who also died in Ghetto were marriedfamily names Lewkowicz, Kajt,Szwarc,Proszczanski, etc.
Kantors and Cantors of USA live in New York, Florida,Detroit etc. and meet for family reunions.
