I will be going to Europe and one of my stops will be the Basque country, which is where our name comes from. There are are couple of spellings but the Guana is not one of them - I've heard Gauna, Gaona, and Guyona. I've always wanted to know so I will be going to the motherland to find out. I am also interviewing a retired professor in Frenso, California who supposedly also wanted to know everything there is to know about our surname and he did it. I will keep you all posted on what I find out.
