Logan's paternal grandfather, Max Lerman, was born in 1927, in Berlin, Germany, to a Jewish family from Poland. They left Germany in the 1930s, because of the Nazi regime, and lived in Shanghai, China, until the late 1940s (in the 1930s and early 1940s, Shanghai took in Jewish refugees). Logan's paternal grandmother, Mina Schwartz, was born in Mexico City, Mexico, to Russian Jewish immigrant parents, Abraham and Zisla.
