Itzhak Meyer Glembovsky - Izzie Glynn comes to America

Hi, Obviously Izzie (Glembovsky) Glynn was named after Sirka and Feiga's father Itzhak Meyer Glembovsky/Glombovsky. I lost a brother Isaac who was also named after him.
Do you know what year Sirka emigrated with her 4 chidren to the USA? What were the parents' names of Izzie (Isidore)????
With the help of Vivien Brodsky's husband, Arye, we were able to piece together much of the info you now see on Geni.....I discovered a lot considering I knew very little to begin with, and need to fill in more missing gaps, if others will be willing to add their input.....
