Barnsley have announced that Paul Conway, Chien Lee, Dickson Lee and Grace Hung have all left the club's board.
Chinese billionaire Chien Lee, Conway and Hung were all part of a consortium that took over at Oakwell in December 2017.
Jean Cryne, the wife of late owner Patrick, has joined the board as a director, along with their son James.
The Tykes were relegated to League One this season.
Jean Cryne told the club website:
"As a collective, we will bring leadership to help the club reach its potential, providing a clear and transparent purpose.
"James and I love this football club and we will continue Patrick's legacy in building a true community club. We are proud Barnsley fans and truly understand the emotion and connections associated with being a Red."
