I am attempting to trace my fathers ancestors. His grandfather (Morris Kletischy - surname might be slightly different) and grandmother (Leah ne Witcowska) were from Kalisz, Poland. They were jews and were 'asked to leave' by the Russians in about 1881/1882. They came to England, along with Morris's brother Isaac, and settled in Whitechapel, London first appearing in the 1891 census. They had a number of children - Lazarus, Abraham, Rose, Solomon (my Grandfather), Rebecca, Hyman & Myra.
After a couple of years Morris changed the family name from Kletischy to Morris (he also changed his first name to James) but my Grandfather (Solomon) changed his surname later from Morris to Reid.
I have been to Kalisz twice and visited the archives office but the records are sparce and mostly in Russian. Can anyone give me advice on where I can continue my quest for information.
