France does not have City Directories as you would in the US. The closest would be City Census. A survey was done every 5 years. Unfortunately, these are not online and are only available at the archives in Bordeaux.
The challenge you will find is that the census is done per city/town and then by street and then household. In other words, you'll have to go through each page of the records book to find the Seligny family. For a city like Bordeaux you are talking about 194,241 people in 1866 and 162,000+ in 1861. Good luck!
Could you please clarify what you are looking for? You write that you want to know if the parents (Michel and Adele) were in Bordeaux before Michel died in 1867. If they left N-O in 1866 so they were in Bordeaux from then.
