Julio and my great grandfather, Jose Leonardo were half brothers (making you and I 3rd cousins.) Their father was Enrique Cuilty Bustamante, son of Gabino Cuilty and Maria Bustamante. I have never seen in my research a connection to Maximillan. I would love to see any info you have on that. My research (and words from my grandmother) was that the Cuilty's left Mexico on orders of Pancho Villa, 'leave with nothing or you will be killed' This was due to the clsoe family ties with Luis Terrazas and his family. Terrazas wife was Carolina Cuilty, sister to Enrique Cuilty Bustamante as well as the fact that Enrique married Luis' niece, Juana Molinar Terrazas (daughter of Luis' sister, Rosa).
