I'm happy you can find new elements.
On the archives municipales de Toulouse website, there are census of population : choose "registres de recensements 1872-1936". http://basededonnees.archives.toulouse.fr/4DCGI/Web_FondsLis...
As Toulouse is a very big town, it's divided into several sections called "cantons" : north, center, west and south.
The difficulty is to find in which canton the adress you look for is situated. (If you want me I read it correctly, give me the link or the reference of the act in which you find it).
Don't hesitate to ask help to the agents of the archives municipales of Toulouse in order they tell you in which canton your adress is. On the first page of the website, click on "contacts" and choose "demande de renseignements". http://www.archives.mairie-toulouse.fr/index.php?id=86
Fill the blancks and send your request. Be the more precise and short you can.
