Caplun Genealogy and Caplun Family History Information

I am looking for any information about the Caplun family that would have lived in or near Bălţi in Moldovan/Romanian (Bessarabia) before WWII. My father is Sukhar (Sukar, also known as Sylvain) Caplun, who immigrated to Rio de Janeiro, Brazil, in 1946. He was accompanied by his mother, Pesca Kanen

Thank you very much, Elizabeth Caplun
