Sorry I can't help. My research has concentrated on the younger brother Rev Rigbye Rigbye that inherited the Harrock estates. My research shows that their father, John, was Rector of North Meols and succeeded to the Harrock estates in 1787, was granted armorial bearings on the 15th of September, 1787, whilst he was the rector of North Meols. He also took the name and Arms of Rigbye by Royal licence.

At John's death, in 1793, he left his Cheshire estates to his eldest son Thomas and the Harrock estate to his third son, the Rev. Rigbye Baldwin who then became the Rev. Rigbye Rigbye.
