In the 1860s, excavations by General Augustus Pitt Rivers uncovered a large number of human skulls, and almost no other bones, in the bed of the Walbrook.
the house is shown in Ogilby and Morgan's ‘Map of London,’ 1677, and in the plan of Walbrook and Dowgate wards in Noorthouck's ‘New History of London’ (p. 612).
The society opened numerous educational institutions, including: St. Joseph's Seminary in Baltimore, to train missionaries for the black missions; Epiphany Apostolic College, Walbrook, Baltimore, a preparatory school for St. Joseph's Seminary; St. Joseph's Catechetical College near Montgomery, Alabama, to train young black men as catechists and teachers; and St. Joseph's Industrial School at Clayton, Delaware, an agricultural and trade school for black youth.
