Ann Lois Davies Romney was born on April 16, 1949, in Michigan.
Mrs. Romney’s grandfather David Davies was a coal miner who worked down the Coegnant Colliery close to his home in the village of Nantyffyllon, near Maesteg, South Wales.  After an injury at the mine, he moved to the United States in 1929, soon earning enough money to send for his family, which consisted of his wife, Annie, and his son, Edward.
The Davies’ eventually had five children, but could only afford to send one to college. That was Edward, who attended General Motors Institute of Technology in Flint, Michigan. Edward met with success, and he eventually settled his family in a wealthy Detroit suburb. He became mayor of Bloomfield Hills. The Romneys have been described as elitist, but Ann Romney took her sons into a Welsh mine to remind them of their roots.
Ann Davies was fifteen when she began dating eighteen-year-old Mitt Romney. Partly because of his influence she converted to The Church of Jesus Christ of Latter-day Saints (erroneously called the “Mormon Church” by the press) in 1966. After attending Brigham Young University and enjoying a semester abroad in Grenoble, France, she married Mitt Romney in 1969 in a civil ceremony and then immediately afterwards in the Salt Lake Mormon Temple. She earned a bachelor’s degree from Harvard Extension University in 1975.
Ann Romney is involved with a number of charities and is an expert horsewoman.
Ann Romney was diagnosed with Mulitple Sclerosis in 1998, but has the syndrome under control and has been able to keep a busy schedule in support of her husband’s presidential bid.
She told of how he had supported her when she found out she had multiple sclerosis, and how he helped get her out of what she called a “deep dark hole” after her diagnosis.
“Not only do I have the absolute conviction that he would be a fantastic president. But I also know that he would have the character and the integrity.”
“He gave me permission really to just accept where I was and to let me move past so I could fight this disease,” said Ann Romney, who has recovered since her 1998 diagnosis through a combination of horseback riding, drugs and alternative therapy. 
Ann Romney has emphasized her husband’s strong values and the fact that he can be counted on at a time of crisis. She was first lady of Massachusetts while Mitt Romney was governor, and campaigned actively for with him during his 2008 bid for the U.S. presidency. In May 2008, she shared with her husband the Canterbury Medal from The Becket Fund for Religious Liberty, for “refus[ing] to compromise their principles and faith” during the campaign.
While Massachusetts First Lady, she was active in teenage pregnancy prevention efforts. In 2005, the governor appointed her as head of a new special office whose purpose was to help the state’s faith-based groups gain more federal monies in association with the White House Office of Faith-Based and Community Initiatives.
