Life
In Uncommon Criminals, we learn that Uncle Charlie and Uncle Eddie left Romania in 1959 as young men, in order to make their way as thieves across Europe. However, Uncle Charlie's native tongue is Russian, so it is possible that he, like the younger members of his family, grew up living a nomadic life in Eastern Europe.

They both fell in love with her and were manipulated by her in their planned heist of the Cleopatra Emerald at the Montreal World Fair in 1967 because of their love for her. As a result, Uncle Charlie and Edde had a falling-out and their relationship would remain tense for decades.
