I am just researching my maternal family, the Suchers, and stumbled upon this message board and your message from four years ago! I don't know if you are still connected to this site so many years later but I will share with you what I know. My maternal great grandfather, Alois Sucher, married Johanna Sommer, maybe a relation to Cecelia. My mother now 93 yrs. old remembers visiting in Graz in 1928 and meeting an aunt Celie and uncle Tony. Could it be these two? Also, Alois Sucher had a daughter, Rosa, who married a George Hallemann. I think maybe this is the same family as yours.
I would love to hear from you.
