I am researching my paternal great grandparents who emigrated to UK in late 1800’s and later went on to end their lives in South Africa. Is there any way I can contact the nearest synagogue where they spent their early lives for information and/or their parents and family? My 1 x GG was Hyman Proctor (Hebrew name Chaim Zelik b Fivish) born in Krosneiwice, Poland in 1868/69 and died 3 Nov 1932 in Boksburg. My 1 x GGM was Rachel Swartz (Hebrew name Moshe bat Leib) born unknown Poland in 1866 and died 6 May 1928 in Boksburg.
