1900 US Census Philadelphia repeated HoH names instead of household members
I searched Historical Records for K* Herwitz and saw an entry for Katie Horwitz, with her name repeated for each family member. See 1900census-Philly_Horwitz-Katie.jpg below.
I followed the link to the image and found the repeated name changed to Raphael Horwitz in the bottom list. See 1900census-Philly_Horwitz-Raphael.jpg below.
