"George Romney was born to American citizens living in a Mormon church colony in Chihuahua, Mexico."

Actually, Romney's parents were NOT US citizens, having been born to parents who left the Utah TERRITORY before statehood. They left the territory because of the ban on polygamy, and settled in that Mormon colony. George Romney was born in 1907, but not to US citizens.

Most of the sources say they were citizens, but I don't see how they could have been. Unless they were US citizens who moved to Utah, thence to Mexico. I suppose that is possible. But they weren't US residents even before moving to Mexico.
