Sir Owen Tudor (Welsh: "Owain ap Maredudd ap Tudur" , 1400 – 2 February 1461) was a Welsh courtier and the second husband of Catherine of Valois (1401–1437), Henry V's widow.
 He was the grandfather of Henry VII, founder of the Tudor dynasty.
 Owen was a descendant of a prominent family from Penmynydd on the Isle of Anglesey, which traces its lineage back to Ednyfed Fychan (d. 1246), a Welsh official and seneschal to the Kingdom of Gwynedd.
 Tudor's grandfather, Tudur ap Goronwy, married Margaret, daughter of Thomas ap Llywelyn ab Owain of Cardiganshire, the last male of the princely house of Deheubarth.
 Margaret's elder sister married Gruffudd Fychan of Glyndyfrdwy, whose son was Owain Glyndŵr.
 Owen's father, Maredudd ap Tudur, and his uncles were prominent in Owain Glyndŵr's revolt against English rule, the Glyndŵr Rising.

 He wrote "Utopia", published in 1516, about the political system of an imaginary ideal island nation.

The John Messer Barn is a historic structure within the Great Smoky Mountains National Park in Sevier County, Tennessee, United States.
 Located along the Porters Creek Trail in the Greenbrier valley, it was constructed in 1875 by Pinkney Whaley.
 The Whaleys later sold their farm to John H. Messer, who was married to Pinkney's cousin, Lucy.
 In the 1930s, the Smoky Mountain Hiking Club, which constructed the Smoky Mountain Hiking Club Cabin nearby, leased the barn from the National Park Service.
 The barn was added to the National Register of Historic Places in 1976, and is the last surviving structure from the pre-park Greenbrier Cove community.

The Welling-Everly Horse Barn is a historic horse barn located west of U.S. Route 136 and northwest of Adair in rural McDonough County, Illinois.
 The barn was built in 1882 for Dave Welling, a wealthy livestock farmer.
 The Stick style barn was noted for its "artistic beauty" in Macomb's daily newspaper; its architecture is typical of the era's focus on building exquisite buildings in rural settings.
 While the barn was originally paired with an Eastlake style farmhouse, the house burned down in the 1890s and was replaced by a Queen Anne house that has since lost its architectural integrity.
 Welling sold his farm to Wm. H. Smith in 1892; in 1901, it was purchased by Jonas Everly, who began farming grain on the property.
The Herman Coors House was once the home of Herman Frederick Coors.
 It was originally built as a modest bungalow in 1915 by Elmer Johnson, a builder who later in 1934 built the brewhouse of the Coors Brewery.
 In 1917 the house was purchased by Coors, a younger son of Adolph Coors, who hired noted area architect Jacques Benedict to transform it into a beautiful and artistic Tudor Revival style home, with a wooden arch front door canopy and stone terracing around.
 Coors was an officer of the Coors Porcelain Company, and in 1921 moved away to Inglewood, California where he established the H.F. Coors Company to manufacture porcelain there.
 The house was then purchased by banker Edward A. Phinney, who owned the Rubey National Bank in downtown Golden.
 He built a companion cottage and barn behind the house in 1928.
 His fortunes took a tragic turn, however, during the Bank Holiday of the Great Depression, when he lost much of his fortune trying to save the bank.
 Since that time the home has remained very well and artistically preserved.
