An Illinois couple this year welcomed their 100th grandchild. Leo and Ruth Zanger of Quincy have 53 grandchildren, 46 great-grandchildren and one great-great-grandchild. The Zangers have been married 59 years and have 12 children. The youngest, 31-year-old Joe, was already an uncle 10 times when he was born. Most of the family lives in the Quincy area. When they get together they rent a church hall and it takes 50 pounds of ham or ten turkeys to feed everyone.
