Richard Nemrod Falkenstein I think he's from W.V.

I have just learned that my great, great-grandmother was Sara Falkenstein from Russia. Are you any relation? She married Tantham Karmitz in Russia and migrated to Ohio. Do you know the origin of the name? Any information is truly appreciated!!!

Hi my Name is Yan and have the Falkenstein Brothers as Friends in West Virginia (terra Alta) Their father was Charles Falkenstein, and his father was Clyde falkenstein,
I am trying to help them trace their roots, I have come across Joseph A Falkenstein (born 1839 Died 1879) who lived at Wheeling in West Virginia (married Amelia Gruen in 1856) Have you any information to help me? Who was Clyde Falkensteins father?
Thanks.
