Hello, I know of the Twins Capitan Andres Bello Leon and Colonel Fernando Bello Leon. Andres Bello Leon was my ggg grandfather. There is also Amado and Andres Leon from the previous generation. Amado Leon was the father of Mercedes Leon Bazan , she married Fernando Bello and had twins Andres and Fernando Bello Leon. Fernando, Andres brother was killed in the war. There is some confusion between two brothers that married two sisters.One was Leon and One was bello.But the confusion lies in the generations prior. we dont know which one. I know Andres Bello Leon is the Son of Fernando Bello and Mercedes Leon Vallejo Bazan.
Mercedes died after the death of her son Fernando. Andres married Maria Toribia Beritan Fernandez and had 10 children .Estrella, Celeste, Serafina, Angel, Andres Bello (POLO), Javier , Esmerada, Manuel,and esusperncia. ( missing one)
There are names for Leonand Bello in the L.D.S. archives , these names were sent in by a Leon Family member that was born in Cuba. Hope this helps.
