Abdullah's estimated birth year

Based on Neville's descriptions of Abdullah as in his late eighties when they met (1929-1931), researchers estimate his birth year at roughly 1845-1848.

Adjudication: Both rows are researcher-derived estimates from the same underlying Neville quote ('in his late eighties' when they met in 1929-1931), not independent evidence, so neither can be called certain. Row 0's wider circa-1846 estimate (~1845-1848) better reflects the genuine imprecision of 'late eighties' than row 1's single-year 1848 calculation, which overstates precision the source doesn't support. Genuinely an estimate, not a settled fact - flagging for human judgment on which approximation to carry forward.
