The de Barsdorpe brothers were members of the Dutch noble family van Borssele, who named themselves after the lordship.
[2] The brothers built a castle and a church, which gave the lordship and village of Baarsdorp a more prestigious aura.
From then on, the lordships of Baarsdorp and Sinoutskerke were owned by the same people but never formally merged.
According to Smallegange, the coat of arms of the lordship of Baarsdorp initially were the coat of arms of a branch of the van Borssele family, and adopted by the lordship after this family died out.
[7] Similar coat of arms were later also used by the municipality of Sinoutskerke and Baarsdorp, with permission of the Dutch High Council of Nobility.
