One opinion says he is born in Cuba, the other position says that information is not right. If you want a balance as you say, you have to find a balance in this arguing by just skipping this information. 
You write on your wikipage you are a humanist, so be that tolerant and respect the opinions of others. You are totally alone with your opinion. No book indicates he is born in Cuba. Your sources are too weak. The way you aruge and act here makes me suspicious that you have an emotional, personal interest by attacking de Zayas. Please leave your personal conflicts outside Wiki. Thanks. MP
