Jacob (or Jacques) I Geubels (d.1605) belonged to a Brussels weaving dynasty founded by Frans, possibly his father, in the 1550s. He owned one of the largest workshops in Brussels, which his widow, Catharina van den Eynde, continued to run in conjunction with their son Jacob II (who signed his works with his full name) until 1629.
Jan II Raes belonged to one of the most important weaver's dynasties of Brussels between 1580 and 1650. The three successive owners of the workshop all had the Christian name Jan, but Jan II was the most important of them. He was granted the privileges in 1613 and 1629 and was burgomaster of Brussels between 1634-35.
