Did Dr. Antonmarchi in Cuba leave any descendants. The earliest Antonmarchi in Puerto Rico was Luis Antonmarchi who may have been Francoise Antonmarchi's brother.
I also have in my family line the Laffitte family from Santiago de Cuba, whose descendants migrated to Ponce, Puerto Rico c. 1897. These Laffffite descend from Pierre, brother of the pirate Jean Lafitte from New Orleans, LA. Another line migrated to San Juan in 1960 after Castro came to power.
