My mother (Evelyn)had a very close friend who was Bertha Oropeza (born in Sucre), she married to an english gentleman, Frank Jones, they had a son, Allan Jones. They went to live to Guatemala many years ago and I don't know what happened with their lives as my parents died and probably Bertha and Frank too. However I believe she was your relative. I remember that she was a very beautyful woman. Black hair, black eyes, white perfect skin. I've seen you are asking also about your Campero ancestors. I'm married to a "tarijeña", perhaps she knows something about your grandparents. I'm sure that some of her oldest relatives know something about your grandparents.
