First an aside: If the Schaefer census data gets put on a website, I hope you will post a notice here! And thank you for your diligence! Does anyone have information about a Maria Schaefer who emigrated to Erie County, PA in1853 or 1854 from Prussia (specifically "Hostbin bei Pottsdam"). She would have been 8 or 9 years old. No idea of parents or siblings but her marriage license was witnessed by a Ferdinand Schaefer and a Carolina Schaefer Heubeck. She married Daniel Serr (em. 1866, Rulzheim), 31Jan1867 in Erie. She was later known as Mary Shaffer Serr until she died in 1935. Any further info on this particular Schaefer family would be greatly appreciated. I'm at a deadend! Laura Prescott Duffy Brookline, NH
