If you were to visit today, this is the Swedish neighborhood where the Wessman family lived in the 1880s through the 1890s. It appears to have been greatly gentrified.
The Swedish Household Examination Books are an excellent genealogical source. Here is the page for the Wessmans. Their entry begins on the top line.
Here is the first part of the entry for the family.
It lists each member of the family with names, exact birth and marriage dates, whether they'd been vaccinated for smallpox (everyone but the baby), and their religious status.

Officials updated the entry yearly. This is the second page showing the name of the neighborhood on the top, Skolgatan 13 and Nygatan 23 (see that corner in the Google Streetview above).
It records their previous residence. If I'm reading it right, they moved within the city to their current location on November 5, 1884. The last columns show Johan moving to a different location and Amanda and the rest of the family moving to America.
