A vocal school, blab school or ABC school or Old-time School was a type of children's primary school in North America, outdated and obsolete as the 19th century progressed.
 The school children recited "(blabbed)" their lessons out loud separately or in chorus with others as a method of learning.
Alexander Parker Crittenden (January 14, 1816 – November 5, 1870) was a 19th century pioneer American attorney and politician, and a member of the influential Crittenden family of Kentucky.
James Wadsworth (April 20, 1768 Durham, Connecticut – June 7, 1844 Geneseo, New York) was an influential and prominent 18th and 19th century pioneer, educator, land speculator, agriculturalist, businessman, and community leader of the early Genesee Valley settlements in Western New York State.

Redwork is a form of American embroidery, also called art needlework, that developed in the 19th century and was particularly popular between 1855 and 1925.
 It traditionally uses red thread, chosen because red dyes were the first commercially available colorfast dyes, in the form of Turkey red embroidery floss.
 Redwork designs are composed of simple stitches and were mainly used to decorate household objects in the 19th and 20th centuries, especially quilts. Patterns for individual quilt blocks were sold for a penny in the United States, making them popular and affordable.
 In the 21st century, redwork has seen a resurgence among crafters.
 The main stitch used in redwork is backstitch or outline stitching, formerly known as Kensington stitch.
 Redwork was a common introductory form of embroidery taught to children in the 19th and 20th century.
 Children would make quilts decorated with redwork motifs, with motifs of various sizes prior to approximately 1910 and uniform sizes after that year.
 It was also a way for women with skills in pattern stamping or embroidery to generate their own source of income from the home.
Antwerp was developed as a fortified city, but very little remains of the 10th century enceinte.
 Only some remains of the first city wall can be seen near the Vleeshuis museum at the corner of Bloedberg and Burchtgracht, and a replica of a "burg" (castle) named "Steen" has been partly rebuilt near the Scheldt-quais during the 19th century.
 Parts of the canals that protected the city between the 12th and 16th century have been covered and used as a sewage system.
 Both the 16th century city walls and the 19th century fortifications have been covered up by major infrastructure works during the 19th and 20th century.
Robert Steere (1833–1910) was a latter 19th century pioneer in California, nine years after U.S. statehood.
 He was a member of the Los Angeles Common Council, the legislative branch of the city government.
The Oregon Trail is a computer game originally developed by Don Rawitsch, Bill Heinemann, and Paul Dillenberger in 1971 and produced by the Minnesota Educational Computing Consortium (MECC) in 1974.
 The original game was designed to teach school children about the realities of 19th-century pioneer life on the Oregon Trail.
 The player assumes the role of a wagon leader guiding a party of settlers from Independence, Missouri, to Oregon's Willamette Valley via a covered wagon in 1848.

 The game is exclusively distributed through Target, although copies are also available via Amazon.com.
 The game components are in the style of 8-bit video games to emulate the look and feel of the original releases.
