You asked if my family originated in Virginia/Washinton,D.C. area and the answer is 'Not that I know of". My grandparents all came to the U.S. from Germany before my parents were born, but I don't know in which year.I believe my surname was originally spelled "Klipper"and Anglishized(sic)when they arrived in the U.S.
My dad was born in 1889 or 1890 and my mom in 1899, both in St.Louis,MO.
I have not had much luck in finding anything under either name, other than some possible relatives around the St.Louis,MO area.
