Lora de Ros, lady of Horton, gave her right to two carucates of land and of woods in Plumstead to the abbot, Thomas, in return for the rights of her and her heirs to partake of prayers performed in the church during 1287. It appears that Robert, the last abbot but one, had recovered a share of this land from her ancestor, Richard de Ros. It was found by a jury of grand assizes that his ancestors held this land in tenancy from the abbot and convent at a rent of twelve pound per annum.
