I am seeking any info anyone has of my great-grandmother Maria Schaefer born (date unknown) in Hostbin bei Pottsdam, Prussia, married Daniel Serr (born Rurlzheim, France) in Fairview, Erie County, PA on 31 Jan 1867 (Marriage witnessed by Johann (Mel---?) Heubeck, Ferdinand Schaefer, and Carolina Hrubeck). The only information I have is a marriage certificate and Daniel's naturalization papers (1880). Thank you! Laura Prescott Duffy
