My great-grandfather, Francisco Semidey, came from Corsica to Puerto Rico. He married Herminia Colon and had (I believe) seven children: Santos, Jose, Pascual, Francisco, Maria Emilia, Julia, and Ana Maria. Maria Emilia was my grandmother.
I would love to e-mail with you about further information you might have found on the Semidey family.
Sincerely, Natascha Otero Santiago
