In a way that relates to the study of family history and lineage.
The family tree was constructed genealogically, tracing back several generations.
Genealogically → It is formed from "genea" (from Greek "genea", meaning generation or descent) and "-logy" (from Greek "logia", meaning study or discourse). The word "genealogically" refers to the study or discourse of generations or family descent.
Think of 'genea' meaning generation and 'logy' meaning study — so genealogically relates to the study of family generations.
