My grandpa, Jose or Joseph Domingo Pagan was born in Yauco, Puerto Rico in May 1878 and died in San Jose in 1971. He was married to Natalia Santiago, who was born in March 1887 and died in 1934. Natalia was also born in Yauco, Puerto Rico.
They had 11 children: Juanita (died at birth), Manuel, Gumerzindo, Jose, Sara, Rebecca, Rachel, Jacobed, Leah, Natanel, and Jonathan (my father).

I am trying to trace their roots back to Puerto Rico. One of the children (Leah) says that Jose or Natalia's parents may be from the Basque region of Spain.
