The Cannon Mills Company was an American textile company founded by James William Cannon, based in Kannapolis, North Carolina.
 It was founded in 1888 and went bankrupt in July 2003.
 The Cannon brands were then purchased by the Iconix Brand Group.
Described as “one of the most important late 18th century plantation houses in Virginia” by the Senior Architectural Historian, Commonwealth of Virginia Department of Historic Resources, Mount Ida was built c. 1795 by William Cannon, on a hill overlooking the south side of the James River near New Canton in Buckingham County, Virginia.
 The site was near the northwest corner of Cumberland County and across the river from Bremo.
 In 1805 Cannon sold the property to the legendary land baron David Ross, who subsequently sold the property to William Leitch, a Buckingham merchant.
 Around 1850, Leitch, laden with tobacco export wealth, added a major addition to the east side of the house, as evidenced by the difference in siding, window size and interior trim.
 The intricate, extraordinary interior woodwork with its elegant and unique composition was designed by a master builder, modeled after patterns found in two early 18th century architectural treatises, William Pain’s Science of Architecture and Asher Benjamin’s Practical House Carpenter.
 While Leitch family lore contends that Irish immigrants performed the work, scholars are of the opinion that the work may have been done by the same skilled craftsman who markedly similar woodwork at Woodlands (1789-1794), originally in Amelia County and since relocated to Goochland County.
 The interior of Mount Ida has been compared to that at Plain Dealing Plantation (circa late 1780’s), another exemplary plantation home a few miles away in Keene.
