The point is a working research result, not a claim of room-level certainty
For the sample chart, we preserve the best current coordinate as the observer point while keeping the evidence status separate. The current target is the historic hospital site associated with the birth record; the precise maternity ward has not yet been pinned down.
Why this is better than a city centroid
A city centroid is convenient but arbitrary for a person who was born at a known facility. Moving to a historically researched facility point makes the coordinate represent an actual birthplace hypothesis rather than the middle of a municipal polygon.
The next research step is architectural
The useful remaining sources are the kinds that can distinguish parts of a medical campus: dated floor plans, maternity-wing announcements, hospital archives, planning records, directories, and historical maps. Sanborn and USGS collections illustrate the kinds of spatial records that can anchor older structures.

The sample stays honest while the research continues
Spatial Press can use 34.172160, -103.347000 today without pretending it is the delivery room. If stronger evidence appears, the coordinate and provenance note can be updated together.
