WE may be on the same track. My grandfather,Charles Otto Lindenberg, lived with Charles Drews [an UncleI believe] when he first came to U.S. from Alsace in 1893. He traveled with his maternal grandmother, _____ Drews [her name may have been Caroline]and his sister and 2 Aunts. They settled in Buffalo, NY. Or, grandfather's mother may have been Caroline Drews Lindenberg -- I haven't been able to trace yet.
Let me know what you think.
