Family name Koenig in Bas Rhin Alsace France

by Dale R. Koenig
(Kansas City, MO. US)

i am looking for relatives of my Great-great grandfather Jacques Koenig born in Bas Rhin Alsace aprox 1835. I've found his father and grandfather; both an Etienne Koenig, both from the same area. But looking to find relatives further back in the Koenig line. This would be prior to 1850 in the same area. Rhin Bas Alsace. Near Gundershoffen and Gumbrechtshoffen.
