1904, Byron Nicholson, Le Canadien‐Français, page 138:
— Oui, ma’ame, j’ai vu ça, mais sûr et certain, je ne suis pas irlandaise, répondit la solliciteuse sans sourciller.
"Yes, missus, I saw that, but sure and certain, I'm not Irish," replied the solicitor without flinching.
Usage notes
This contraction, chiefly used to convey a non-native speaker's pronunciation or contraction of madame, fell out of use during the 20th century. The usual French contraction of madame is m'dame.
