Transcription notes:
- Both entries appear on the same index page (page 1141 of the GRO index volume).
- William Pownceby's birth was registered in Whitechapel, Vol. II, Page 537.
- Edwin Pownceby's birth was registered in St George in the East, Vol. II, Page 94.
- The two districts are adjacent East London parishes, consistent with siblings born to
  the same family in the same year or different years within the same quarterly index.
- Both registrations are in Vol. II, suggesting the same registration quarter/year.
- If Edwin and William are siblings born to the same Pownceby parent, the different
  districts (Whitechapel vs. St George in the East) may reflect where the birth was
  reported or a family move between registrations.
- Walter George Ponceby's 1901 Boston marriage record names his father as "Edwin Pownceby"
  — Edwin is therefore the Pownceby who continued the line to Walter and then Donald Edwin Ponceby.
  William's relationship to the main archive line is unconfirmed.

Context for archive research:
- "Whitechapel" registration district covered Whitechapel, Mile End, and surrounding East London areas.
- "St George in the East" covered Wapping and Stepney areas of East London.
- Both were heavily populated working-class parishes in 1840.
- GRO certificate reference for William: Vol. II, Page 537, Whitechapel, 1840.
  The full birth certificate (with parents' names) can be ordered from the GRO to confirm parentage.
