Dear Seth and other FrenchSigers,

The references you found in the "Tables Decennales" of the Bulletin des Lois
concern the "partie supplementaire", not the "partie principale". The
Naturalizations appears in the "partie supplementaire".
The volume 49 you found on line of Gallica website concerns the "partie
principale".
The volume 49 and the others of the "partie supplémentaire" you need are not
on line.

Best regards,
Laurence Abensur-Hazan (Mrs)
