Hi,
My mother is a DeMouy.
My Grandmother was Rosina Berger DeMouy from Mansura,LA.
Her parents were Rodolphe Berger & Eugenia Reynaud.
I have a picture of my Great Great Grandmother -
Paulin Guigonet/Geugoinaet (not sure of spelling) who was Eugenie Reynaud's mother.

I am researching both lines of my family, but have not been able to connect much past my grandparents.I know that both grandparents were from families w/9 siblings and there were several marriages between the two families.

Louise L. Roquette married Arthur DeMouy in 1874 and were my grandfather Harry T.DeMouy's parents.
I am sure we must be related and would love to collaborate,
please contact me @ marjulf@hotmail.com or 678-887-4262.
