If your grandfather was married to Lorida Marie Galliano, then I believe that I may be able to help you with some more info...
I have your grandfather's name as "Maxime Paul Danos"
I show his parents as Joseph Clet Danos & Sedonia Marie Bruce.
I show Joseph Clet's parents as Augustin Joseph Danos, Sr. and Louisa Marguerite Guidry.
I show Augustin's parents as being Urbain Danos and Melasie Marie Mire.
I can keep going further back if this sounds like the correct Maxime that you're looking for.
