In 1938, Reagan co-starred in the film Brother Rat with actress Jane Wyman (1917–2007). They announced their engagement at the Chicago Theatre and married on January 26, 1940, at the Wee Kirk o' the Heather church in Glendale, California. Together they had two biological children, Maureen (1941–2001) and Christine (b. in 1947 but lived only one day), and adopted a third, Michael (b. 1945). After the couple had arguments about Reagan's political ambitions, Wyman filed for divorce in 1948, citing a distraction due to her husband's Screen Actors Guild union duties; the divorce was finalized in 1949. Wyman, who was a registered Republican, also stated that their break-up was due to a difference in politics (Reagan was still a Democrat at the time).
