I am looking for descendants of Emil A. Mayer b. 1862 in Baden, Germany and Helen Preyer, b. 1869, Pforzheim, Baden, Germany.I do not know if they married in Germany or the USA.They had four daughters while living in Pennsylvania - Frieda b. 1892, Marie b. 1895, Helen b. 1897, and Emma b. 1900.The US Census records show that they lived in New Jersey for several years, the last town being Delanco (1930) and from another source Delanco as late as 1947 which is where Ilose them.
