I am a little puzzled? Your Berrys resided in New Orleans but changed their name to Metz?
My George Berry is the son of my GGrandfather, Claburen P. Berry, born abt. 1845 in Georgia. Claburen married Louisa E. Hays/Hayes, born abt. Jan 1839, also born in Georgia.
Apparently, George was born abt. 1868, unknown location. His younger brother, my Grandfather, William (Willie) Claborn Berry, migrated from Georgia to Arkansas.
I don't know if the whole family migrated or if it was just Willie. Perhaps the other brothers and sisters migrated to other states?
I do not have any records, other than a list of Claburen Louisa's children, of which George is one.
