Model Tree
An inferred pedigree reconstructed from census links — up to 4 generations within the 1900–1950 window. Closer generations are built from household co-residence; deeper ones are bridged by following a relative to their own childhood census. Confidence compounds and weakens with each generation.
Our Model Tree links Grace Jones across 3 US Census years (1920, 1930 and 1940) in 2 locations, using XGBoost record linkage.
