Hello again!
I found three of the children of Sabin Valerio (born in Atripalda, Avellino, Campania) and Louise (not Laura) Candelmo (not Cantelino). I tried finding them in the 1881, 1886 and 1891 censuses using the addresses from the birth records but no luck. I ran into the same problem as I did back when I tried to find the Manfredonias in the censuses. I could find the streets but the sections with their addresses weren't included.
Here is a link to the censuses:
http://www.archives13.fr/archives13/CG13/cache/bypass/pid/49... There's small type in red that says:
Lien vers le site externe 'Accéder aux documents des listes nominatives du recensement
Click on that and it will open the search. The censuses are not searchable by name, only by address or area, so it takes a lot of patience.
I'm attaching the three birth records. They are:
1. Angeline Josephine Valerio born 17 March 1884. Sabin and Louise were both 22. They lived at 213 Grand Chemin d'Aix. The Manfredonias were living at 217 Grand Chemin d'Aix on the records I found for them. So basically next door.
2. Seraphim Bastiste Valerio born 14 March 1887. His parents were 26. They lived at 8 Traverse du Moulin à Vent.
3. Albert Antoine Valerio born 6 February 1889. His parents were 29. They lived at 61 rue Vallon Montebello.
Hope that's some help.
Cheers,
Soosi
