The Pierrepont mansion stood at the foot of Montague Street. It was built by John Cornell, and became Pierrepont property in 1802. Hezekiah Pierrepont was a dignified and influential member of a community in which his exertions were always for broad and public-spirited plans. Teunis Joralemon, who had been a harness-maker in Flatbush, bought part of the Livingston estate, on which he practiced market gardening. He filled the offices of justice of the peace and Trustee, and other offices, but was of a temperament antipodal to that of Pierrepont, hotly opposing new streets, especially through his own property, and scorning the distinction of having Joralemon Street named after him. Another prominent estate was that of the Fleets. The name of Bergen is prominently associated with the progress of the village. At Bedford Corners were the Meseroles, Ryersons, Lefferts, Vandervoorts, Suydams, Tiebouts, Cowenhovens, and other old families. In December, 1821, the subject of removing the court house from Flatbush to Brooklyn was agitated in the papers, and on the 21st of January, 1825, a meeting was held at Duflons, whereat a committee was appointed to obtain the removal of the court house and jail from Flatbush to Brooklyn. In 1826 the subject was brought to the attention of the Legislature, and that body passed an act that the court of common pleas and general sessions should alternate between Flatbush and the Apprentices' Library Building in Cranberry Street, then just finished. The court of common pleas in those days corresponded to the county court of our time. The county clerk's office was removed to Brooklyn in March, 1819. The county court began to hold sessions in Brooklyn in January, 1827. The Trustees of the village of Brooklyn deemed a debtors' prison a very important addition to the city. On the 19th of February, 1829, Joseph Sprague, president of the Board of Trustees, made a report on the subject of fitting up under the market a prison-room for debtors. In accordance therewith a lockup was provided and cells built under the market. These cells were oftentimes crowded, and but little provision was made for the comfort of the occupants. The Bridge approach now passes over the old lockup. During those early days prisoners were also confined in cells in the almshouse, then situated on the south side of Nassau Street, between Bridge and Jay streets. The building is still standing, and has been converted into dwellings.
