>Is there a census for PA or Beaver County for the years 1865-90? I'm looking >for McDonald's, Whisler's and Jackson's. there are the federal censuses, done in 1860, 1870, 1880. the 1890 census was destroyed by fire. there is a 1900 census. you can find these at the library in Beaver Falls, the Carnegie Library in Pittsburgh, or probably from any LDS Family History Center. hth, JoAnn.
