In this week's episode of This Is the Gospel, Jeff says he only knew three things about his grandfather George growing up. One, he was born in the former Yugoslavia in a country that is now called Montenegro. Two, George was raised in Worland, Wyoming. Three, he had changed his last name from Mijušković to Marks. That was all. Any other attempt to get any information regarding family history from his grandfather led to a command to, "Shish." But after a chance encounter on a humanitarian aid trip to Haiti, Jeff slowly began finding breadcrumbs that led to his Mijušković line. And so after a killer deal on airfare, Jeff found himself in his family's homeland armed with a letter written in Montenegrin and an unquenchable desire to discover his own family history.
