Good lord. Is this what I'm up against? Looking at an entire page, if not book, indexed incorrectly. Should be Ward 1, Philadelphia 1900 census, instead links to Northumberland, PA. No wonder it's not been fixed.
@GregoryMorris7 - Sadly, there is a current problem with the 1900 census that the engineers are working on. Please see the following thread - United States Census, 1900 Problems
There are instructions on how to report the issue in that thread.
Thanks for your patience and for coming to the community for help. :)
