- I assumed they lived at a certain house in 1880 because they lived there in an 1890 city directory.
- I assumed there were no changes to the numbering of houses on that street.
After a quick search of the 1880 census at Ancestry.com turned up nothing for my Marsch family in Baltimore, I decided to check the original pages myself to see if they were missed in the index. I knew the family was living at 205 South Chapel Street (near Pratt Street) in 1890 so I assumed they lived at the same address in 1880. I headed over to Steve Morse's excellent resource to narrow down the Enumeration District for the address where I assumed they lived.
I found South Chapel Street near Pratt in district 10 so I went back to Ancestry to take a look at all of the census pages for ED 10. I eventually found the street, but the house numbers did not correspond to what I had expected. Hmm. I posted a query in the Baltimore message board at Ancestry to see if anyone had insight into what I was missing. Several helpful people quickly replied and it turns out the house numbers changed in 1887. One kind person even told me to look for house #54! So, back to the images. What did I discover? There was no 54! The even numbered side of the street seemed to start at 56.
So it's back to the drawing board as I search for my Marsch family in 1880. I know the family arrived in Baltimore in August 1879. I know they were living on South Chapel Street in 1890. Where were they in 1880? The mystery continues...
