The world’s largest family is set to expand again next month with the arrival of three babies at the clan’s four-story mansion in Mizoram, northeast India.

Pu Ziona, the 69-year-old leader of the 35,000-strong Chana Pawl Christian sect, has 39 wives ranging in age from 32 to 73. The family itself has lost track of precisely how big it is.

According to the World Record Academy, the Zionas became the world’s largest family in 2011 with 181 members, including 94 children and 33 grandchildren.
