Daniel Rojas Lanus is searching for his ancestors in the United States, probably descendants of Jean Lanusse Cazenave who was born in Prechacq-Navarrenx June 21, 1786 (died ?) and emigrated to Argentina around 1814. He was the son of Pierre Lanusse Saint Gerons, born in Prechacq-Navarrex, Bearn, district of Orthez, south of France May 18, 1759 and Jeanne Cazenave, born ?) 

Jean emigrated to Argentina at the time Napoleon invaded Spain. As it was not wise to land as a frenchman, he converted his surname to LANUS (which is more of a spanish form). He married on Oct 15, 1815 Doña Teresa Jacinta Calixta Fernandez de Castro, born August 14, 1793 and died on April 3, 1853. 

They had 6 children :
1.  Leopoldo, 2.  Anacarsis, 3. Teófilo,  4.  Rosa, 5.  Juan and  6.  Lucio.

About 1827 he decided to make trips to Islas Malvinas along with Governor Luis Vernet . Soon thereafter he dissappeared without a trace.
Some people say that he emigrated to Cuba. Some others say it was to the U.S. since he owned land and plantations in the south. We have information that he owned some black slaves who adopted his name after him.

There is also a U.S.  family who bears the name LANUS (descendants from ancestors from Alsace-Lorraine) who contacted us once. The name Lanus does not exist in Spain and is reputed to be only to the descendants of Jean de Lanusse Cazenave in Argentina. 

Information and documents would be of great value and very much appreciated.
