History
Native Americans are known to have resided in the region in pre-Columbian times based on artifacts found in the Ulmstead Point area dating back to the Archaic period (5000–1500 BC). Later tribes that have been in the area include the Algonquin tribes, among others. Arrowheads and other artifacts have been found in the Briarcliff area. However, when Captain John Smith arrived in the area in 1608, he reported no Natives. Following the establishment of Anne Arundell County (now Anne Arundel County) in 1650, much of the land that later became Arnold lay within a large proprietary land grant known as Swan Neck, which encompassed substantial portions of the Broadneck Peninsula. Governor William Stone granted Swan Neck to Edward Lloyd I, Commander of Anne Arundell County, and over time portions of the grant were subdivided and transferred. By the early nineteenth century, one such subdivision had become known as Rayland, an agricultural estate containing all of the frontage of what is now Arnold's along the Severn River, from the modern communities of Rugby Hall at the north to Pines-on-the-Severn at the south. The early settlement of Arnold, an area between the Magothy and Severn rivers, began with the farm of John Arnold. He was a veteran of the War of 1812, who acquired on the north side of the Severn River. One of his sons, Thomas Arnold, inherited the land, later working as the local station master for the Baltimore and Annapolis Short Line Railroad. Residents know the area to have been home to a racetrack in the present-day Revell-Downs planned community and even a rollercoaster and boardwalk in Mago Vista Beach.
