Hi, I have some additional information to update my earlier message. Although I have no more information on my ggrandfather Gustave Kettner's origins, I have found that his wife Philomene Huck (not Houck) was born in Bischoffsheim, Bas Rhin, Alsace in 1853 and may have emigrated from Le Havre, France to New York City in 1881. Gustave (not Gustav) Kettner is found in the 1884 Philadelphia, PA City Directory and died in 1886. A French researcher could find no evidence of his being from Alsace, so we suspect he may be from Germany near the Rhine River. His son Gustave moved to southern California in the 1940's.
