Newell and Avery write in their biography, "When Emma Hale awoke on a Thursday morning, January 18, 1827, she did not plan to be married by evening." 
"Joseph. . .had asked for Emma's hand twice and had been rebuffed—not by Emma, but by her father."  Emma and Joseph again discussed marriage while visiting the Stowell home that day. Later in life Emma relates, "Preferring to marry him to any other man I knew, I consented." 
Before the day was over Joseph and Emma were married at South Bainbridge, New York. 
In Emma's 1835 hymnal she included only one hymn on marrage (See transcription of When Earth was Dress'd in Beauty as printed in 1835 hymnal).
