Harry T. Burn was the youngest member of the Tennessee House of Representatives in 1920 when the vote was called on the suffrage amendment. Burn had been heavily courted by the Anti’s and regularly wore their red rose as a symbol of his No vote on suffrage. When his unanticipated “aye” vote broke the tie and pushed women’s suffrage in over the finish line, finally ratifying the Nineteenth Amendment, the surprised “Suffs” crowd erupted in cheers.

The press kept asking Mr. Burn why he changed his mind. He read them the telegram his mother sent him: ““Hurrah, and vote for suffrage! Don’t keep them in doubt. ...be a good boy and help Mrs. Catt put the 'rat' in ratification." https://www.history.com/news/the-mother-who-saved-suffrage-passing-the-19th-amendment
