Although most women these days are deciding to have fewer children, there are still some huge families out there. Leo and Ruth Zanger of Quincy, Ill., are a perfect example of this; they recently welcomed their 100th grandchild to the world.

Born on April 8, Jaxton Leo Zanger is actually the couple’s 46th great-grandchild, joining a cast of 53 grandchildren and one great-great grandchild. “The good lord has just kept sending them,” Leo told the Quincy Herald-Whig. “We could start our own town.” And with the couple’s willingness to have more (There’s always room for one more,” Ruth said), that might just happen soon. After all, most of the family still lives in the Quincy area, where they rent a church hall for family get-togethers.

How did the family get so big? Well, Leo and Ruth, who have been married for 59 years now, had 12 children between 1956 and 1984. Their oldest child, Linda, 58, had her first child — and Leo and Ruth’s first grandchild — at 19 years old. By the time their youngest child Joe, now 31, was born, he was already an uncle to 10 kids.

Many of today’s parents cite career and education, as well as the costs of raising kids as their reasons for having fewer kids. In the United States, most women can expect to have about 2.1 children. But while this may be true, there is some evidence that large families work out. As The Wall Street Journal reports, having more kids ends up paying off as the children get older. They can teach each other skills, and may eventually begin helping out financially. The more kids there are, the more they’re likely to help. This is a model the Zangers practice; each one has a duty when it comes to those family get-togethers.
