Quietly heroic and deeply devout, Julia Abegg Call was the fourth wife in a polygamous marriage to Anson Bowen Call, Mormon bishop of Colonia Dublan in revolutionary-era Mexico. In her book "The Fourth Wife," author Carolyn O’Bagy Davis offers an intimate look into a polygamous family that struggled to stay together amid political turmoil in Mexico and the growing intolerance toward polygamy in the United States. Call became the mother of 12 children and confronted danger, poverty, prejudice and personal tragedy as the Call family found themselves in the middle of warring parties during the Mexican Revolution, crossing paths with both Pancho Villa and General Pershing.
