Okay, historical fiction author here doing some research. How many of those many 'bridge' songs you listed date from the early 1800s? Definintely before 1880, preferably before 1850. I'm specifically looking for a song, not necessarily with 'bridge' in the title but having to do with a bridge, and it would be great if it was in French or of French origin. New Orleans origin/Cajun French would do too. Any suggestions?
