Question:
David "Davy" Crockett (August 17, 1786 - March 6, 1836) was a 19th-century American folk hero, frontiersman, soldier, and politician. He is commonly referred to in popular culture by the epithet "King of the Wild Frontier". He represented Tennessee in the U.S. House of Representatives and served in the Texas Revolution. Crockett grew up in East Tennessee, where he gained a reputation for hunting and storytelling.
Crockett fell in love with John Canady's niece Amy Summer, who was engaged to Canady's son Robert. While serving as part of the wedding party, Crockett met Margaret Elder. He persuaded her to marry him, and a marriage contract was drawn up on October 21, 1805. Margaret had also become engaged to another young man at the same time and married him instead.  He met Polly Finley and her mother Jean at a harvest festival. Although friendly towards him in the beginning, Jean Finley eventually felt Crockett was not the man for her daughter. Crockett declared his intentions to marry Polly, regardless of whether the ceremony was allowed to take place in her parents' home or had to be performed elsewhere. He arranged for a justice of the peace and took out a marriage license on August 12, 1806. On August 16, he rode to Polly's house with family and friends, determined to ride off with Polly to be married elsewhere. Polly's father pleaded with Crockett to have the wedding in the Finley home. Crockett agreed only after Jean apologized for her past treatment of him.  The newlyweds settled on land near Polly's parents, and their first child, John Wesley Crockett, who became a United States Congressman, was born July 10, 1807. Their second child, William Finley Crockett, was born November 25, 1808. In October 1811, the family relocated to Lincoln County. Their third child Margaret Finley (Polly) Crockett was born on November 25, 1812. The Crocketts then moved to Franklin County in 1813. He named the new home on Beans Creek "Kentuck".  His wife died in March 1815, and Crockett asked his brother John and his sister-in-law to move in with him to help care for the children. That same year, he married the widow Elizabeth Patton, who had a daughter, Margaret Ann, and a son, George. David and Elizabeth's son, Robert Patton, was born September 16, 1816. Daughter Rebecca Elvira was born December 25, 1818. Daughter Matilda was born August 2, 1821.

Question:
The Greeks (Greek: Ellenes) have been identified by many ethnonyms. The most common native ethnonym is "Hellen" (Ellen), pl. Hellenes (Ellenes); the name "Greeks" (Latin: Graeci) was used by the Ancient Romans and gradually entered the European languages through its use in Latin. The mythological patriarch Hellen is the named progenitor of the Greek peoples; his descendants the Aeolians, Dorians, Achaeans and Ionians correspond to the main Greek tribes and to the main dialects spoken in Greece and Asia Minor (Anatolia).
There is currently no satisfactory etymology for the name Hellenes. Some scholars assert that the name of the priests of Zeus in Dodona, "Selloi" (Selloi; also Elloi Helloi), changed to Sellanes (by analogy with Akarnanes) and then to Hellanes and Hellenes. This theory is based on Aristotle's comments in Meteorologica where he places Ancient Hellas in Epirus between Dodona and the Achelous river, where in his opinion the great deluge of Deucalion must have occurred. The land was inhabited by Selloi and Graeci, who later came to be known as Hellenes. In that regard Graici (Graikoi) was a native name of a Dorian tribe in Epirus which was used by the Illyrians. Homer mentions that the Selloi were the prophets of Zeus at Dodona, but he is referring to Zeus of Dodona as god of the Pelasgians who were Pre-Dorian populations. It is possible that the extension of a particular cult of Zeus in Dodona (a tendency among the Greeks to form ever-larger communities and amphictionies) caused the name to further extend to the rest of the peninsula.  However, this theory connects the name Hellenes with the Dorians who occupied Epirus, and the relation with the name Greeks given by the Romans becomes uncertain. The toponyms, especially an ancient city Hellas in southern Thessaly and the Greek tradition indicate that the name Hellenes is Pre-Dorian and that it is more likely that the homeland of the Graikoi who were later called Hellenes was in central Greece. The Greek tradition mentions an earlier deluge of Ogyges in the region of Boeotia which was occupied by the Minyans a group of autochthonous or Proto-Greek speaking people. The region was called Graike in ancient times probably after the old city of Graea (from Proto-Greek grau-j-, "old lady") on the coast.  Homer refers to Hellenes as an originally relatively small tribe settled in Thessalic Phthia. During the era of the Trojan War they were centered along the settlements of Alos, Alope, Trachis, and the Pelasgian Argos. This Homeric Hellas is expressly described as "kalligunaikos", kalligynaikos, "of beautiful women", and its warriors, the Hellenes, along with the feared Myrmidons, were under the command of Achilles. The Parian Chronicle mentions that Phthia was the homeland of the Hellenes and that this name was given to those previously called Greeks (Graikoi).Alcman (7th century BC) also refers that the mothers of Hellenes were Graikoi. In Greek mythology, Hellen, the patriarch of Hellenes, was son of Deucalion, who ruled around Phthia with Pyrrha, the only survivors after the great deluge. It seems that the myth was invented when the Greek tribes started to separate from each other in certain areas of Greece and it indicates their common origin. The name Hellenes was probably used by the Greeks with the establishment of the Great Amphictyonic League. This was an ancient association of Greek tribes with twelve founders which was organized to protect the great temples of Apollo in Delphi (Phocis) and of Demeter near Thermopylae (Locris). According to legend it was founded after the Trojan War, by the eponymous Amphictyon, brother of Hellen.
