I got your messages. Sorry it took forever to get back to you, but I actually only stumbled on that site, and rarely went back. What you say is interesting. My "Jomarron" part of the family also originated on the island in Holguin or at least in Oriente province. I think at around the turn of the century, they moved to the other extreme, Pinar del Rio, where the other three branches of my family would soon end up as well.
I am a great-grandson of one Julio Jomarrón, who married Adela Pintado in Pinar del Rio, and had a string of girls, one of which, Concepción Jomarrón-Pintado, is my paternal grandmother. I don't know off-the-bat what Julio's father's name was, but I'm sure I knew at one time, and can certainly still find out.
