I believe that your father and I are half-brothers. I've heard of Lalo and Mike' but never got to know them. By the time I was old enough "to ask question", your dad was in SAntonio. My regards to your aunt Angie. Yes, your grand-father was a player, personally "a bad one", not caring for his offspring. Please share with me what your father remembers of Eladio....> have him tell you about the yellow bus...and Zubiate's Cafe-(cantina) a hot spot/joint known as "La Calle Cuatro" (4th street).
Let's work together to trace our roots, at least to the mid 1850's back to Chi-wa-wa (mispelled).
