My cousin says his father changed his name to kac although he still had to serve as a cossack . Their relatives are in
santteandre and sao paulo brazil as well as belgium and the brazilian kibbuytz in israel. Most are drs. in brazil but i have been unable to get through any embassy -they must block it.
I have tried emailing a rabbi but no response. Gershom left
usa with sons to brazil. Any new information since last posting?
