Hello,
Sorry for the late reply but hope you're still browsing the internets for more info. I came across lots of people with the, Vivas last name on myspace initially. It prompted me to search broadly on google and found similar hits with people from Venezuela. I've asked my family back in Guatemala, as i'm currently in the US, and they don't know anyone from Venezuela as well. Most readings I've done states that it's a baroque regional last name but was spelled, Vives. I've read on and have known one person with the Vives last name. Apparently the spelling changed as people migrated to the New Spain (Central and South America).
So personally, I've been on that quest to find my Venezuelan connection but have still come up short. Some of my family are also, Salvadorean so who knows at this point. But I still like the fact that not too many people have the last name. Hope you continue your quest and find it joyful like me.
PS. I'll be sure to come back here and read more just in case there's more info or replies.
