I am interested in the Zaks of Radlyvyliv. I am trying to see if there is a connection to the Zaks of Varniai Lithuania. My Great Grandfather Ber Movsha Zacks (born 1853) and his father Iosel first appear in Varniai in 1890 on tax lists. Perhaps they fled Radlyvyliv due to the pogroms of 1880 in Ukraine. Most of the first names on the 1850 Russian revision list for Zaks are the same as in Varniai . My Grandfather Isack born 1902) had 9 siblings. I am going to search for more list for the period 1853 and 1890
