Hello, I have a great great aunt named Marcelina, and her siblings were Juan,Dolores, Francisco, Maria, & Emilo. Marcelina was born around 1881. Her Parents were Ramon Hernandez & Carmen Escafuller Rosado ( not sure if she was adopted by Ramon & Carmen. But My G-grandfathers name was Francisco Hernandez and his wife was M. Piedad Casteneda. I don't know if Francisco & Piedad adopted. As she was about the same age as Francisco. Could be a connection, but not sure. Email me if you think this could help you in any way.
