Texas ? Authorities who removed 219 women and children from a polygamist compound were struggling Sunday to determine whether they had the 16-year-old girl whose report of an underage marriage led them to raid the sprawling rural property.

Many people at the compound, built by followers of jailed polygamist leader Warren Jeffs, are related to one another and share similar names; investigators said in some case they were giving different names at different times.

Investigators on Sunday bused them out of Eldorado, nearly 200 miles northwest of San Antonio, as other law enforcement agents continued to search for more children and evidence at the 1,700-acre compound, the former site of an exotic game ranch.

State troopers armed with a search warrant raided the compound on Friday to look for evidence of a marriage between the girl, who allegedly had a baby at 15, and a 50-year-old man. Under Texas law, girls younger than 16 cannot marry, even with parental approval.
