Rosemount, County Down


Eng. rose + mount (originally a house-name)


Rosemount is the name which Sir James Montgomery gave to a defended house he built in 1634 to the south of the present village of Greyabbey.  Apparently Rosemount was a popular name for houses in Ireland and Scotland at this time.  The earliest recorded spelling of Rosemount is Mountross which is taken from the Funeral Entry of Catherine, first wife of James Montgomery in 1634.  It is unlikely that the name Mountross was ever in common use and its elements appear to have been deliberately reversed to give it an air of sophistication. Montgomery received a grant from the crown on 19th March 1638 of all the lands he then had in his possession in the parish of Grey Abbey and the house-name Rosemount came to be applied to the manor.  The original building was burnt down in 1695 and another house was constructed on or near the same site some time before 1744.   After the erection of this second house it seems that the name Grayabbey House came to be used alongside Rosemount (Montgomery MSS 1-2 n. 3; Knox Hist. 482; ASCD 263, 405-8).
