Legacy transcription retained without substantive editing; rendered current reference profile variants documented in the Phase 10 evidence snapshot.
The exact rendered source heading “John H Callahan” is preserved separately from the canonical display form “John H. Callahan.”. The current reference profile records Company B, 122d Illinois Infantry; the inherited record identifies Company H. Both unit values remain preserved, with Company B controlling the current canonical field. The current historical action-place wording replaces only the controlled canonical geocoder field; the complete inherited place remains preserved.
