Data Quality Notes

  • Source: FamilySearch.org shared Family Tree (collaborative, user-contributed)
  • Geocoding: FamilySearch Places API + Nominatim/OpenStreetMap fallback
  • Reliability by generation:
Generations Era Reliability
1–12 ~1700s onward High — civil/church records
13–18 ~1400s–1600s Medium — English/European gentry records
19–30 ~1000s–1400s Low — noble/royal chronicles
30+ Before 1000 Very low — legendary/traditional
  • Welsh patronymic surnames (Ieuan, Gruffudd, Dafydd) dominate both trees due to deep Welsh ancestry
  • Walter's maternal side: Only 5 ancestors recorded — significant gap for future research
  • ~8,000 bad geocodes cleaned: Pre-1492 pins in Americas, southern hemisphere artifacts removed
  • 82% overlap: Unusually high shared ancestry due to convergence in medieval English/Welsh nobility
