John MacSeonin Burke (Seán MacSeóinín de Búrca), aka John de Burgo, O.S.A., Archbishop of Tuam 1441 to 1450.
John Appleton (1815–1864) was an American Assistant Secretary of State and Democratic Party politician from Maine.
Lea Laboratory is a historic laboratory building located on the original campus of Wake Forest University at Wake Forest, Wake County, North Carolina.
 It was designed by noted Baltimore architect John Appleton Wilson (1851–1927) and built in 1887–1888.
 It consists of a two-story pedimented central brick block, three bays wide and seven deep flanked by one-story pedimented brick wings.
 The building has a blend of Colonial Revival and Victorian design elements.
 It is the oldest remaining building on the original campus of Wake Forest University, now Southeastern Baptist Theological Seminary, and was one of the first chemical laboratories constructed on a Southern college campus.
John Appleton (February 11, 1815 – August 22, 1864) was an American lawyer, politician and diplomat who served as the United States' first "chargé d'affaires" to Bolivia, and later as special envoy to Great Britain and Russia.
 Born in Beverly, Massachusetts, Appleton graduated from Bowdoin College in 1834 and attended Harvard Law School from 1835 to 1836.
 On leaving Harvard, he became a barrister and newspaper editor while maintaining a vigorous involvement in Democratic politics.
 In 1840 he was appointed as registrar of probates for Cumberland County, Maine, and in 1845 became Chief Clerk for the United States Department of the Navy.
Stuck was born in Appleton, Wisconsin and went to Appleton North High School.
 She received her bachelor's and master's degrees from University of Wisconsin–Oshkosh.
 Stuck was a rural mail carrier and worked at the Appleton Housing Authority.
John de Leche (or John de Leck or John de Leek) (died 1313) was a canon of Dunkeld and prelate during the early 14th century.
 After the death of Matthew de Crambeth, Bishop of Dunkeld, in 1309, William Sinclair was elected by some of the chapter to the bishopric.
 John de Leche, however, was elected soon afterwards, and had the support of King Edward II of England.
 The diocese of Dunkeld lay vacant for three years, while the issue was contested at the Papal see.
 Pope Clement V appointed James, Cardinal Deacon of St George in Velabro, to judge the issue; but this was resolved when, on 22 May 1311, John de Leche was promoted to the Archbishopric of Dublin.
 He held the latter for two years.
 He obtained a charter for the earliest University in Dublin in 1311 but his death, which seems to have been sudden, in 1313 greatly hampered the establishment of the university, which never flourished.
