When did Edouard Manet marry Suzanne Leenhoff both month and year?

On October 28, 1863, Manet married Suzanne Leenhoff. She was a musician that had been hired by Manet's father to give Edouard and his brother piano lessons. Edouard and Suzanne had a ten year relationship before they were finally married in 1863. During their ten year relationship, Suzanne gave birth to a son, Leon Koella. The father is most certainly Manet, but Leon was presented to other people as Suzanne's younger brother.
