- The title Northern Central Railway will be used for simplicity in reference to the railroad. However several companies have owned the right of way, The line was built by the York and Maryland Line Railroad in 1837-8. This and several regional lines were consolidated late in 1854 to become the Northern Central Railway Co. The name was retained as the Northern Central Railway Division when the Baltimore and Ohio purchased it around 1855 and, soon afterward, when the Pennsylvania Railroad Co. took over in 1860. A second set of tracks was laid by this company in 1871. The Division was sold to the Commonwealth in 1976 and thereafter transferred to the County of York.
- The first rope walk was built in the "Meadows" in 1848. A second building, built in 1850, on the current location was destroyed by fire only two years later.
- However these are only idealized prototypes. Germanic plans show increasing influence of Georgian design principals through time, such as facade symmetry and an internal circulation hall. This acculturation process mixes design traditions creating several unique plan types in the Pennsylvania German cultural region. Examples include the common plan with four bays, two doors and four rooms, often called a German 4/4 and a plan with three rooms and a hall, one off-center door and four bays. Proper identification of these features often requires access to the interior. Furthermore, the development of these mixed design traditions has never been adequately documented and no common nomenclature yet exists. Because of these difficulties, identification as Germanic or Georgian is necessarily indeterminate. The number of bays and number and location of entrances is noted in the comments section of the inventory to aid in this identification. See Henry Glassie, "Eighteenth Century Cultural Process in Delaware Valley Folk Building." In Common Places: Readings in American Vernacular Architecture, Dell Upton and John Michael Vlach, eds. (Athens, Ga.: The University of Georgia Press, 1986).
