In Tanzania, one man has done enough breeding to create his own small village. Mzee Ernesto Muinuchi Kapinga is currently married to sixteen women. With those sixteen women, Kapinga has had 104 children. From those 104 children spawned 144 grandchildren. In his homestead, Kapinga says each of his wives has their own home, and there are people in the village who are charged with helping out with various chores and helping tend to the children running around. It’s also worth noting that at one point, there were 20 wives, but some opted to leave, and others passed away. Oh…and seven of his current wives are sisters, so there’s that.
