The property to the west of the Barracks (Franciscan Convent) is listed as Moncrief's Quarter. The buildings along Convent are listed on a lot that measured 612' on Covert Way and 212' along Convent Lane. This property originally belonged to Richard Henderson, but he became bankrupt. He was indebted to Charles Ogilvie, and he took the land in exchange for the debt. Two of the buildings were constructed of stone. These building were unoccupied for ten years until after the beginning of the Revolutionary War when British Loyalists were evacuated from Georgia.
The open groves to the south of these buildings were gardens and groves. This lot was owned by Captain William Jenkins.
The other building west of the barracks along the south side of Convent Lane belonged to Pedro Fernandez and his wife Josepha Baesse at the end of the First Spanish Period. At the time the house was a one-story coquina structure with a flat roof. Fernandez and his wife along with their two children departed with the rest of the Spanish in 1763. The property was put up for sale, and was managed by Jesse Fish. At some time after 1763 the house was extensively renovated with the addition of a fireplace, a second floor, and the distinctive exterior staircase on the south side of the building.
By 1783 the owner of the property was Nicholas Turnbull, a minor government official. Turnbull had been granted the house by Governor Patrick Tonyn for a yearly rent of one peppercorn, and the requirement that he make some improvements to the property, which he had done by 1783.
