I see that you found on your trip a picture of a graveof Israel Sperling, I know that my great Aunt MerleSperling(originally Rokeach or Kochkovsky) was marriedto a Phineas Sperling and they had two children :Fishel and Hester, The Rumor is that they died in theWarsaw ghetto but that source also says that they diedwith Merle and Phineas and my grandmother wrote in hermemories that she died of an illness and left her twochildren orphaned with her husband.
A picture of my mother at age two with her family before leaving Vilkaviskis - on the second floor on the porch, They lived at 7 Eimcio Latve - onthe map from before the 2nd world war after a discussion with a 94 year old survivor who lived near them but did not remeber them - as they left in 1926this is very possible - he claims that on the map the brick building in his day would have been the library and Hapoalim Club but on the map that side of the street is even numbers and as you can see on the map my Uncle z"l drew the number was 7 in any case it must have been close because it is just down the street from the market which we remember my grandmother and uncles talking as being very close.
From Vilkaviskis about February-March 1926 just before my mother left Vilkavisikis with her family . She is the little girl standing in the middle . Her Brother Israel is standing on the left and the second from the right standing is her brother Sam Berz(Bercas). We think the others are friends but maybe they are relatives. If any one recognizes them please tell us. We have a possible name for one of the little girls standing on the left- it may have been Sperling?
