Aurelius Ambrosius, better known in English as Saint Ambrose (c. between 337 and 340 – 4 April 397), was a bishop of Milan who became one of the most influential ecclesiastical figures of the 4th century. He was one of the four original doctors of the Church.

Ambrose was born into a Roman Christian family between about 337 and 340 and was raised in Trier. His father was Aurelius Ambrosius, the praetorian prefect of Gaul; his mother was a woman of intellect and piety. Ambrose's siblings, Satyrus (who is the subject of Ambrose's De excessu fratris Satyri) and Marcellina, are also venerated as saints. There is a legend that as an infant, a swarm of bees settled on his face while he lay in his cradle, leaving behind a drop of honey. His father considered this a sign of his future eloquence and honeyed tongue. For this reason, bees and beehives often appear in the saint's symbology.

After the early death of his father, Ambrose followed his father's career. He was educated in Rome, studying literature, law, and rhetoric.Praetor Anicius Probus first gave him a place in the council and then in about 372 made him consular prefect or "Governor" of Liguria and Emilia, with headquarters at Milan, which was then (beside Rome) the second capital in Italy.

Ambrose Everett Burnside (May 23, 1824 – September 13, 1881) was an American soldier, railroad executive, inventor, industrialist, and politician from Rhode Island, serving as governor and a U.S. Senator. As a Union Army general in the American Civil War, he conducted successful campaigns in North Carolina and East Tennessee but was defeated in the disastrous Battle of Fredericksburg and Battle of the Crater, earning his reputation as one of the most incompetent generals of the war. His distinctive style of facial hair is now known as sideburns, derived from his last name.

Burnside was born in Liberty, Indiana, the fourth of nine children of Edghill and Pamela (or Pamilia) Brown Burnside, a family of Scottish origin. His great-great-grandfather Robert Burnside (1725–1775) was born in Scotland and settled in the Province of South Carolina. His father, a native of South Carolina, was a slave owner who freed his slaves when he relocated to Indiana. Ambrose attended Liberty Seminary as a young boy, but his education was interrupted when his mother died in 1841; he was apprenticed to a local tailor, eventually becoming a partner in the business. His interest in military affairs and his father's political connections obtained an appointment to the United States Military Academy in 1843. He graduated in 1847, ranking 18th in a class of 38, and was commissioned a brevet second lieutenant in the 2nd U.S. Artillery. He traveled to Veracruz for the Mexican-American War but arrived after hostilities ceased and performed mostly garrison duty around Mexico City.
