Francis Muriel Lillie was daughter of John Lillie, an Irishman who had immigrated to Canada after retiring from being a British soldier in India. Her mother, Lucy-Ann Shaw, was much younger than her husband and had sung professionally with little success. Her mother was the driving stage mother for both the sisters. She attend Gladstone Avenue Public School where her role model, Alexander Muir, was the principle and the composer and lyricist of the 1867 patrotic song, “The Maple Leaf Forever.” While being in their early teens, the sisters with their mother formed the "Lillie Trio,” and sung romantic ballads at local soirees and did a bit of touring in Ontario. Unlike her sister and mother, she wanted to be a classic concert pianist. In November 1910, she placed third in an Canada-British Isles competition, Musical Canada and performed in concert on March 19, 1908. She entered a music conservatory but left to wed on October 22, 1912 John D. Burnett, heir to a Canadian grocery and china manufacturing business. Shortly after her marriage, she and her mother travel from Canada to Germany for her to study music but World War I halted that plan; they went to England instead. The next year 1914, her sister, Beatrice, joined them in England. While Beatrice headed for the stage, she headed for the piano. She composed for Andrea Charlot's “Revue" the 1919 song "Take Me Back to the Land of the Promise," which was sung by Gitz Rice and the 1925 songs " Susannah's Squeaking Shoes" and "Mouse, Mouse." which was sung by her sister. She would later contribute to her sister's later revues with “Tabs” at the Vaudeville Theater in 1919 and “The Charlotte Revue” at the New York City Selwyn Theater in 1925. Other revue songs she composed were “A Little Flat” and “Nine O'clock Revue.” Bing Crosby recorded ”Susannah's Squeaking Shoes” on February 5, 1947. She divorced Burnett in 1926. Her second marriage was in March of 1928 to Arthur Edward Pearse Brome Weigall, an English Egyptologist and talented song lyric writer. In Weigall's novel “The Not Impossible” the character of the set-design Moria had the fact-based personality of Muriel. While she composed the music, Weigall did the lyrics to “Susannah's Squeaking Shoes.” After Weigall's death, she married in 1937 Brian Kenneth Dean Paul, 6th Baronet Paul of Rodborough. She was described as being fiery and quick tempered. In November 2008 “An Evening with Beatrice Lillie” was released and among the collection of songs was "Maud," which was written by Muriel Lillie.
