My grandmother was Hazel Solana Bryan, her dad was William Solana (also Guillaume) and her mother was Fannie Carter Solana. My dad, Cole Bryan, and grandmother traced our family back to the same origins as yours. We go through Manuel Solana, who built what is now Casa de Solana on Aviles St., though we always called it the Charlotte St. house because that's the side the original public front door was. He also had a bunch of descendants on the Masters' side, as his first wife re-married and their children took the step-father's name from what I remember.
Do you trace through him as well? If you do, you might want to look into Los Floridanos, a group of people descended from him and the one Sanchez that stayed through the last English occupation.
