Jacques D'Arc, born 1380 and died 1431, was a free laborer of Domremy born at Ceffonds, near Montier, in Des (upper Marne). Jacques married Isabelle de Vouthon (born 1387, died 1468), called Romee, in year 1405. Their known children were Jacquemin, Jean, Pierre, Catherine, and Jeanne (Joan of Arc).

King Charles VII ennobled Jacques and Isabelle's family on 29 December 1429 with an inheritable symbolic denomination. The Chamber of Accounts, in France, registered the family's designation to nobility on 20 January 1430. Jacques D'Arc de Lys and Jacques D'Arc du Lys are the most common forms of his name with such symbol appended.
