Is anyone researching Euphelia BONNVILLAIN?

Here's what I have and I am hoping you might be able to add to this:

Euphelia was born in Terrebonne, Louisiana and died December 29, 1925. She is the daughter of Pierre Marcellin Bonvillain & Emilie Thibodeaux.

She married Antoine Phillipe LANZON on June 14, 1849 in Terrebonne, LA.
