Hi, Cindy!
My people are from the Cienfuegos area. A long time ago Villa Clara and Cienfuegos were combined into the province of Las Villas, actually, and Las Villas included Zuleta; so I suppose there is a likelyhood that your husbands ancestors are related to mine via both surnames. By the way, I don't understand your husband's mothers full surname; shouldn't it begin with Capote, that being his maternal surname? Do you give her the del Valle surname because she was married to a del Valle? If that is the case, her name should be something like this:
Francisca Capote (+her maternal surname) de del Valle. Hope this helps.
