Bishop’s antecedents are unknown and the return recording his election to Parliament provides the earliest definite reference to him. His later appointment as a tax collector confirms his place of residence.
There is nothing else known about the MP, although there were Bishops living in or near Wycombe in later years. In 1454, a court held at Bassetsbury, the duchy of Lancaster manor embracing most of the borough, took a presentment against Henry Bishop and two others for taking fish from the King’s waters at Wycombe, without licence and at night. Henry was probably a relative of the MP, as perhaps was the John Bishop of Hughenden (just to the north of Wycombe) who died in 1509. In his will, this John set aside money for repairs to the parish church and its Lady chapel at Wycombe.
