I am searching for relatives in Montevideo. My great-great-grandfather was Pierre Casenave. He left the Pyrenees region of France and settled in Los Angeles, California, USA approximately 1860. He received correspondence from his brother in France, Arnaud Casenave. The letters refer to the "family in Montevideo." I am wondering what part of the family may have left France for Uruguay and what became of them. Please contact me if you have any information. Thank you!
