In 1885, he moved to Mexico with his plural wives to escape persecution for these polygamous marriages. He helped to build Colonia Juarez and was its first Bishop, presiding for 12 years. He helped with the building of the telegraph line. He established several businesses and was financially interested in most of the industries started in the colonies, including mining. He helped lay out and build roads into the Sierra Madre Mountains and locate the towns of Corralles and Pacheco.

George felt heartbreak and pain when he heard of the death of his first wife, Phoebe. She had contracted cholera morbus, a particularly bad type of dysentery, and had passed away rather suddenly on August 14, 1892, in Panguitch. It was impossible for him to make the long journey back to Panguitch before her burial, so she was laid away without his having seen her for several years. Her work was done now, and her reward won. He was happy for her, but he knew he would feel a pain whenever he thought of her and realized all over again that she would no longer be there waiting for him.

After moving to Mexico, Maggie (his second wife), gave him two more children: Minerva Elizabeth, and Phoebe Vilate. Martha Ann was the mother of five more: William Exile, Nelle Jane, Moses Thatcher, Martha Ann, and Lola Myrl. Then in 1895, Maggie had another child, Leon Lorenzo, and although she was happy with her new baby, her health was failing and she was not able to work as she had always done. When it was known for certain that she was suffering with cancer, George prepared to take her back to Utah to a doctor there, hoping to get some relief for Maggie. They took the baby with them, and George made the miles count the best he could. They were just a few miles from their destination, Loa, in Wayne County, when Maggie passed away. George went immediately to Panguitch, and there laid her to rest in the cemetery near his first wife, Phoebe, who had gone on some five years previous.

On his return to Mexico, he moved Martha Ann out to the farm. She had borne him another little girl in 1896, and moving out to the farm with her family, now complete with little Una Bernetta, meant she would have to care for all Maggie’s children, as well as take up the chores there. George enlarged their house, for it was not large enough to accommodate all the family. With the larger house, he knew Martha would manage the job of mothering them all like an expert, and so she did.

George again became fired up with the spirit of accomplishment. He felt that he must get busy while he was still able, and get things in order. He couldn’t spend his time living in the past, so new projects quickly started forming in his mind. But the work he cut out for himself was too strenuous for a man of his years and he tired easily. He had frequent spells of illness and he had to turn the job of driving his teams over to his son, George Thomas.

From the mountain country where he had been working, he returned to Colonia Juarez to rest up and hoped to get feeling a little stronger. He soon became restless and went back up to Colonia Chuichupa to see how things were getting on, arriving tired and ill and in such a state that Tom had to bring him back home. His heart was failing and he suffered terribly with diabetes.

It was disheartening to see him, a man so full of the desire to work and build, and who had made such great strides in life and living, lying there so tired and still, the strength of his body being steadily drawn from him. He called his family to his bedside and talked to each of them of the things that were most dear to him. It had ever been his greatest pleasure to bear his testimony of the Gospel, and he would in his good-natured way, conclude, "It took a miracle to convert me, but it hasn’t taken others to keep me converted."

Finally on June 22, 1902, after a very full and complete life, he passed away at his home in Colonia Juarez, and was buried there the next day. Years later, Martha Ann was laid by his side, thus closing the book on the life of George Washington Sevy. He was married three times, and was the father of 30 children.
