Meaning of Osteria

[Jean Galata]

I'm having difficulty with a phrase in a death record. A nine day old baby died and the death certificate says she died, "...nel osteria di ragione del Signore Isidoro Carli."
The only definition I could find for osteria is tavern or public house. It seems unlikely that a newborn would die in a tavern. Can anyone enlighten me on this? The date of death was March 16, 1813. Perhaps the meaning of the word has changed since then.

To understand, we need to understand the phrase in context.
The child could be the son of the owner of the tavern. Was the Tavern owned by Signore Isidoro Carli? Was he also the father?
An 'osteria' translated is bar or tavern, but even today Italians take their children everywhere. Babysitters aren't used unless it's Grandma. If the mother was working at the 'osteria' she might well have had her child with her so she could be breastfed on demand. (the only way). Maybe she and her husband owned the 'osteria'.

...or maybe something happened to the child out of the tavern, and was taken inside for rescue.
Anyway, we'd better see the document...
