Goesaert v. Cleary: Goesaert v. Cleary, 335 U.S. 464 (1948), was a United States Supreme Court case in which the Court upheld a Michigan law, which prohibited women from being licensed as a bartender in all cities having a population of 50,000 or more unless their father or husband owned the establishment.  Valentine Goesaert, the plaintiff in the case, challenged the law on the ground that it infringed on the Fourteenth Amendment's Equal Protection Clause.  Speaking for the majority, Justice Felix Frankfurter affirmed the judgment of the Detroit district court and upheld the constitutionality of the state law.  The state argued that since the profession of bartending could potentially lead to moral and social problems for women, it was within the state's power to bar them from working as bartenders.  Only when the owner of the bar was a sufficiently close relative to the women bartender could it be guaranteed that such immorality would not be present.

Vilicus: Vilicus (Greek: ἐπίτροπος ), was a servant who had the superintendence of the villa rustica, and of all the business of the farm, except the cattle, which were under the care of the magister pecoris.  The duties of the vilicus were to follow the estate owner's instructions, and to govern the slaves with moderation, never to leave the villa except to go on market, to have no intercourse with soothsayers, to take care of the cattle and the implements of husbandry, and to manage all the operations of the farm villa.  His duties and those of his wife (the vilica) are described by Columella (I.8, XI.1, and XII.1), and by Cato (cxlii-cxliii, focusing on the vilica).

John Murphy (fiddle player): John (Boss) Murphy (1875–1955) from The Leap, Churchtown, Co.  Cork was a former farmer by profession, but possessed a keen interest in fiddle playing, and was renowned locally for his ability on the instrument.  His father, William Murphy (1829–1911), was both a fiddle player and maker, indeed John was the proud owner of an instrument that had been made by his father.  John’s father was his first fiddle teacher.  His siblings, a brother and three sisters, also played the instrument but their interest in music waned as they reached adulthood and they did not continue to play.  John’s musical literacy was also gained primarily from his father, who had learnt to read music at a hedge school at Ballygrace in the locality taught by a Thomas Croke.  The same Thomas Croke, many years later, stayed for long periods of time in the Murphy household and would undoubtedly also have taught the young John directly.
