Yani Gellman is an American and Canadian actor. He was born in Miami. His mother, Marilyn (James), is Australian, and his father, David Henry Gellman, was Canadian.
An article that described Yani as being of Jewish heritage also stated that he was “Born to a Russian-English father from Toronto and a Spanish-English mother from Australia.” His father’s parents were both Jewish (from Russia and England). It is not clear from this description if his mother is of Jewish heritage as well. Some web sites describe Yani as having Sephardi Jewish ancestry.
He was named after a family friend, writer Jan Joors.
Because of his father’s work as a reporter, the family frequently moved during Yani’s childhood, living in Australia, Spain, and Texas, before settling in Toronto, Canada.
Yani’s paternal grandfather was Morris Gellman (the son of David Gelman and Esther Kitz/Kotz). Morris was a Russian Jewish immigrant.
Yani’s paternal grandmother was Annie/Anne Miller (the daughter of Isack Miller and Deborah Seltzer). Annie was born in Leeds, Yorkshire, England, to Russian Jewish parents.
