Wichinsky family

My grandparents, Molly and who I'll refer to as "the grandfather", are surrounded by their 3 daughters, with my mother Anna on the left, the eldest Sarah, and Bella on the right.
Molly and Anna immigrated from SOKOLY, LOMZA, POLAND thru Ellis Island in 1921 under the name WIEZISKY but used WICHINSKY thereafter.
Molly [nee KAPLAN] had a first marriage [Jopack/Yopack] but seems to have been widowed a 2nd time to "the grandfather" by the time the family settled here in Milwaukee.
Gravestones for the 3 sisters show their father had given name Avraham Dov.
I have tried searches of FamilySearch, MyHeritage, JRI-Poland, and JewishGen.
