Searching Zawelowicz family from Koidanov, Minsk, Belarus #belarus

My gf, Leib Zawelowicz (Zavelovich) emigrated to Philadelphia in 1899. He eventually helped other relatives to come to the U.S. Upon entry, they changed their name to Cohen. Would appreciate knowing of relatives in Philadelphia. Other family members stayed in Russia and perished in the Holocaust. They possibly died in the 1941 Koidanov Massacre of 1941.
Any knowledge would be most welcomed. Thank you.
