Looking for parents and siblings of my gr. grandfather, Frank GROSJEAN (do not know names). Frank was born abt. 1847 in Alsace, Lorraine, France. I do not know exact birth date or place. He immigrated to America some time in year 1853. Known places he lived were Albany, New York, and Muscatine, Iowa, before settling in Mariposa, California, where he married my gr. grandmother, Mary SOUZA. Any help would be greatly appreciated. Thank you.
