Lucas Faydherbe was the first son of Hendrik Faydherbe and his second wife Cornelia Franchoys. His mother came from an artist family: her father was the successful painter Lucas Franchoys the Elder and her brothers Lucas and Peter were also accomplished painters. His father's sister Maria Faydherbe was recognised as a talented sculptor. Faydherbe's father ran a workshop for decorative sculpture and alabaster carving. Here Lucas learned the basics of sculpture. His father died when Lucas was twelve years old. His mother remarried with the sculptor Maximilian Labbé a year later. Lucas continued his training under Labbé.
