Here is the Ann Romney Bio from Wikipedia:
Born Ann Lois Davies,she was raised in Bloomfield Hills, Michigan, by parents Edward R. Davies and Lois Davies. She has two brothers. Her father, originally from Caerau near Bridgend, Wales, was a self-made businessman who in 1946 co-founded Jered Industries, a maker of heavy machinery for marine use located in Troy, Michigan. He had also held the part-time position of Mayor of Bloomfield Hills. Raised in the Welsh Congregationalists, he had become strongly opposed to all organized religion, although on her request the family very occasionally attended church, and she nominally identified as an Episcopalian. At times she helped out at her father’s plant.
Ann Davies knew of Mitt Romney since elementary school. She went to the private Kingswood School in Bloomfield Hills, which was the sister school to the all-boys Cranbrook School that he attended. The two were re-introduced and began dating in March 1965; they informally agreed to marriage after his senior prom in June 1965.
While he was attending Stanford University for a year and then was away starting two-and-a-half years of Mormon missionary duty in France, she decided on her own to convert to The Church of Jesus Christ of Latter-day Saints during 1966. In doing so she accepted the guidance of Mitt’s father George Romney, the Governor of Michigan. George included her in Romney family events while
Mitt was away; she appreciated his treating her as an equal and picked him to baptize her.
Ann graduated from high school in 1967 and began attending Brigham Young University (BYU). She also spent a semester at the University of Grenoble in France during her freshman year and was there during the 1968 Winter Olympics. The Mormon missionary rules allowed her only two brief visits with Mitt and very rare telephone calls with him. She involved herself in campus life at BYU, spending several days a week as a volunteer in the academic affairs office. While at BYU, she dated future business academic Kim S. Cameron. She sent Mitt a “Dear John letter” of sorts, while Mitt sent letters back imploring her to wait for him.
Immediately after Romney’s return from France in December 1968, the pair reconnected and agreed to get married as soon as possible. Ann Davies and Mitt Romney were married in a civil ceremony on March 21, 1969, at her Bloomfield Hills home, with a reception afterward at the Bloomfield Hills Country Club. It was presided over by Edwin B. Jones, a banker and Romney family friend then serving as an LDS Church Regional representative of the Twelve. Among the 250–300 guests were U.S. House Minority Leader Gerald Ford and automotive executives such as Semon Knudsen and Edward Cole, and President Richard Nixon sent congratulations. The following day the couple flew to Utah for a wedding ceremony inside the Salt Lake Temple; her parents could not attend since they were non-Mormons, but were present at a subsequent wedding breakfast held for them across the street. (Both her brothers converted to Mormonism within a year of her doing so. Her mother converted just before her death in 1993. Her father never did, but the family performed a baptism for the dead regarding him a year after his 1992 death
