I need to wait until you post, then I don’t need to.
I've been meaning to bring this up - notice anything unusual about this list? Out of the 10 families living in the apt house/building, there are 4 married women without their husbands. This just wasn't done back in those days. Also, Mary wasn't listed but Joseph was. None of the residents have a spouse or other family member listed. In other years and directories, all adults along with their occupation are listed so why not this one?
Considering there were also at least a couple children living there, that's a boatload of people living in what was supposed to hold only 4 apartments. Fine, some may be roommates but if Mary is missing then we can assume others are also not listed. Too many inconsistencies and questions.
