Hello,
I have been keeping in touch with a woman her name is Argentina Iriarte, originally from Panama. Her fathers name is Manuel Reginald Iriarte. His mother's name is Pabla Iriarte. She cannot remember her grandfathers name. I don't have her e-mail address readily available but I will tell her that you are seeking information on your grandfather. E-mail me when you can and I will do the same as soon as I contact Argentina.
Good Luck,
Larry
