The Last of the Clan McDuck is a Scrooge McDuck comic by Don Rosa.
 It is the first of the original 12 chapters in the series "The Life and Times of Scrooge McDuck".
 The story takes place from 1877 to 1880 when Scrooge is a child in Scotland.
 He comes in conflict with The Whiskervilles, earns his Number One Dime and heads for the United States on a cattle boat.
The Clan McDuck is a fictional Scottish clan of cartoon ducks from which Disney character Scrooge McDuck is descended.
 Within the Donald Duck universe, the clan is related to the American Duck family through the marriage of Hortense McDuck and Quackmore Duck, Donald's parents.
An over-frock coat is an overcoat designed to be worn over a frock coat as an overcoat in cold weather.
 A top-frock coat is also worn over a frock coat in milder weather.
 Shaped like the body coats popular in the late Victorian and Edwardian periods, the over-frock coat was cut in essentially the same way as the frock coat that was worn under it, although it would be larger overall to accommodate the frock-coat worn underneath.
 Like the frock coat, the over-frock would be single-breasted, with step lapels for informal occasions, like business, and double-breasted, with pointed lapels for formal occasions - weddings, funerals, balls, &c.
 The formal variety was known as a 'Prince Albert' overcoat.
 A frock-overcoat, like a frock coat, almost never has pockets.
A surtout coat is a man's frock coat, of the kind worn by cavalry officers over their uniforms in the 18th and early 19th centuries.
 It was occasionally worn by British soldiers during the Revolutionary War (American War of Independence).
A Bluecoat school is a type of charity school, the first of which was founded in the 16th century.
 Most of these have closed, some remain open as schools, often on different sites, and some of the original buildings have been adapted for other purposes.
 They are known as "bluecoat schools" because of the distinctive blue uniform originally worn by the pupils.
 The colour blue was traditionally the colour of charity, and was a common colour for clothing at the time.
 The uniform included a blue frock coat, and yellow stockings with white bands.
Scrooge McDuck is a fictional character created in 1947 by Carl Barks during his time as a work-for-hire for The Walt Disney Company.
 Scrooge is an elderly Scottish anthropomorphic Pekin duck with a yellow-orange bill, legs, and feet.
 He typically wears a red or blue frock coat, top hat, pince-nez glasses, and spats.
 He is portrayed in animations as speaking with a Scottish accent.
A duffel coat, or duffle coat (standard UK spelling), is a coat made from duffel, a coarse, thick, woollen material.
 The name derives from Duffel, a town in the province of Antwerp in Belgium where the material originated.
 Duffel bags were originally made from the same material.
 The duffel coat may have initially come from the Polish military frock coat, which was developed in the 1820s.
 The hood and toggle fastenings proved popular and it spread across Europe by the 1850s.
 By 1890 it was being supplied to the British Royal Navy, and Field Marshal Montgomery was a famous wearer of the coat in World War II.
 After the war, the coats became available as government surplus stock and became popular, especially with students.
A frock coat is a man's coat characterised by a knee-length skirt (often cut just above the knee) all around the base, popular during the Victorian and Edwardian periods.
 The double-breasted style is sometimes called a Prince Albert (after the consort to Queen Victoria).
 The frock coat is a fitted, long-sleeved coat with a centre vent at the back, and some features unusual in post-Victorian dress.
 These include the reverse collar and lapels, where the outer edge of the lapel is cut from a separate piece of cloth from the main body, and also a high degree of waist suppression, where the coat's diameter round the waist is much less than round the chest.
 This is achieved by a high horizontal waist seam with side bodies, which are extra panels of fabric above the waist used to pull in the naturally cylindrical drape.
The 41st New York Volunteer Infantry Regiment was an infantry regiment that served in the American Civil War.
 They were nicknamed Dekalbs Zouaves for their gaudy French/American zouave style.
 Consisting of a dark blue and green zouave jacket with red trimmings, dark blue pantaloons with red braiding, a sky blue sash, a dark blue zouave vest with red trimming, a red tassled fez with a thin yellow band around it, and white gaiters.
 The 41st New York Volunteer Infantry, was first formed to rebel against the Union when talks of secession were under talk.
 The regiment succeeded becoming known for their connections with the confederacy although, they were stopped early in the war and turned over to fight for the Union.
 They were also the only "zouave" regiment in the 11th Corps.
 The regiment also wore a uniform that was based on the Jaeger uniform of Germany.
 It consisted of a dark green frock coat with red trimming and cuff flaps, dark green pants with a red stripe down the leg, a dark green kepi with a red band, and black shoes.
