Hals was an ancient and honourable patrician family, intimately connected with Haarlem for well-nigh three hundred years. The name first appears in the annals of the city in 1350, and again and again individuals bearing it held the offices of Burgomaster, Treasurer, and Schepen—Alderman or Magistrate.

Pieter Claes Hals, Franz' father, was appointed a magistrate in 1575. In 1577 he was one of the Regenten, or Governors of the city Orphanage, and in 1578 he became President of that famous institution.

His profession has not been indicated, but that he was a loyal and influential citizen is proved by his holding a command in the garrison which so heroically defended the city against the Spaniards in 1572.

Wholesale pillage by the hated invader, however, reduced many a wealthy burgher family to penury, and compelled them to seek the recovery of their fortunes elsewhere.

The venerable city of Antwerp, by reason of the enterprise of her merchants, offered great attractions. Thither fled many a Haarlemer, and among them went forth Mijnheer Schepen Hals and his newly married wife. It must have been a great trial to domesticated Lysbeth Coper to have to pack up what was left of their household crocks and seek a new home.

It was in the spring of 1579, a little more than a year after their wedding day, that they started upon their journey. They made first for Mechlin, where a branch of the family was settled, and they were welcomed with cordial hospitality by their relatives.
