I have the family bible of AUGUST PETER/PIERRE JAUREGUIBERRY
with some information on the JAUREGUIBERRY family in N.O.LA
One of his children was born in MEXICO in 1878. Peter married FREDERIKA WILHELMINA KAUDER in N.O. La. They changed their names to PETER J. BERRY AND RICA BERRY. They also lived in Galveston, Tx. I think Peter's father's name was FRANCIS LUCIAN JAUREGUIBERRY b. 1/8/1840 and he died 3/28/1886 in New Orleans, La. Perhaps these people are related to your JAUREGUIBERRY. I do have a picture of Peter and his wife Rica and would be glad to send a copy via email if you would like it.
Hope to hear from you soon.
