Here is the entry in Elmes' A Topographical Dictionary of London and its Environs (1831):
"Chapter-House-Court, St. Paul's Church-yard, is on the north side of the church-yard, at the corner of the Chapter-house, whence it derives its name; it leads into Paternoster-row, by the side of the Chapter coffee-house, and opposite Ivy-lane." (page 115)
