I don't know how much help I will be, but my great -great grandmother Juana Alarcon Perez emigrated from Almeria Spain in 1920 with her two sons; Anotnio Cespedes Perez and Salvador Cespedes Perez. They moved to Canton, Ohio to live with other members of the Alarcon family and her husband, Juan Cespedes.
After they immigrated to the States, they changed their names respectively to:
Jennie Alarcon Cespedes
Antonio Cespedes
Salvador Cespedes (my great grandfather)
I am looking for information on the Alarcon family, as well, if your pedigree somehow links with mine.
