Hello Janie,
I tried to send an email, but it bounced back. The names you listed match up with names provided by my father's aunt Aurora (Dora). She would be Petra's cousin.
The names she could recall were Rumaldo, Ricardo, Pablo, Jesusa, and Ramon (my great grandfather).
Rumaldo children are Petra, Apolonia, Santiago, Heriberto, and Oscar. (I believe these names appear on the 1920 and 1930 US Census).
Ricardo married Josefa, their children are Pablo, Nicolas, Elvira, Evangelina, and Santos.
Pablo married Soledad "Chole", they had a child named Altagracia. (Pablo and Altagracia are buried in Pharr, TX)
Jesusa never married, no children.
Ramon married Guadalupe Ortega. Their children are Pablo, Luisa, Julian, Ramon Jr., Francisca, Rodolfo, Celestino, Lola, Eulogio, and Aurora. (Ramon and Guadalupe are also buried in Pharr, TX.)
Please post a response here, or click on my name above to see my email address.
