That's what I thought at first, but one of the flues that's covered hits
my roof clearly... the other one is not so clear.

Also, I agree that if it were a fireplace flue it would be on the other
side of the roof, near my radiator vent/flue. But wouldn't they have
had flues for the stoves back in 1896? I think so... all the roofs in
the hood have multiple roofed over protrusions that I assume were flues
for a variety of heating/cooking devices.

Anyway, best bet is probably to ask the neighbors and figure out who the
owner is and see if he knows.

Ben, all the openings belong to your neighbor. Your chimney is on the other
side of your house . The four openings represent original connections to
the fireplaces on each floor in the same house. The chimney probably
predates central heating and one of the flues was converted to be used by
the boiler when it was installed.
