How do I take an address and figure out what ward / district / etc. for censuses prior to 1870? I'm trying to find the census for St. Vincent's Orphanage in 1860. It's at Division and Lafeyette St in Baltimore City, and is the Western District (nowadays) in the Upton neighborhood. I thought there used to be something at the archives so you could figure out what the boundaries are for the E.Ds, and I thought it was true for the wards and districts, as well.
