she who entangles

I haven't done this in a while, so here are more meanings of my characters' names (at betwixt_rpg and euphorialane - emphasis in italics).

Johnathan Troy
Johnathan: Hebrew origin, variant of 'Jonathan.' "Gift of God." The son of King Saul, Jonathan was noted for his manliness, generosity, and unselfishness. He saved David's life when Saul would have killed him. My ex-boyfriend's spelled his name this way, so I immediately was drawn to this character. I've also always loved the story of David and Jonathan in the Bible as well, so he was made as a very good friend to Joel Cresswell in the game.
Troy: Of Irish and Gaelic origin. "Descendant of the footsoldier." It was a surname given to those who migrated to England from the French city of Troyes after the Norman conquest of 1066. As a given name, Troy may derive from the ancient Greek city where the Trojan wars were fought. (link)

Justin Finch-Fletchley
Justin: Latin origin, derived from 'Justinus,' which is from 'Justus.' "Just, upright, and righteous." Saint Justin (second century) was a Greek philosopher who wrote of the moral values of Christianity. He was later beheaded in Rome.
Finch: English origin. The bird itself is a small songbird with a short stout bill adapted for crushing seeds (link). In the Middle Ages this bird had a reputation for stupidity. It may perhaps also in part represent a metonymic occupational name for someone who caught finches and sold them as songsters or for the cooking pot. The surname is found in all parts of Britain but is most common in Lancashire. (link) The term "finch" is slang for "to swindle a simpleton". (link)
Fletchley: Origin unknown. Means "field of arrow-heads" or "maker of arrows."

There's a very interesting description of Justin here, which is quoted below:

Justin Finch-Fletchley holds out the hand of friendship to Harry Potter in the first week of their second year, but it will be another three years before this friendship ripens. In a very few words, we have a strong portrait of Justin: to his core, he is an aristocrat of Muggle society, a very English gentleman, whose good manners are as natural as his breathing. His parents are probably a ‘Sir’ and ‘Lady’, and they almost certainly own a country estate – let’s say in Northamptonshire, where the squires and spires, the green hills and flowing rivers, are a couple of hours (in the Rolls Royce) away from London. Attending Hogwarts means that Justin has to miss out on many of the local community events: the Rothwell Fair and the Crick Boat Show clash with his annual exams, while the British Grand Prix is held in the autumn term. But the Northampton Balloon Festival would remain a highlight of his summer holidays.

Justin was once on the waiting list for Eton College, the ultimate aristocratic boarding school – he would have been two years ahead of Prince William. When he persuades his parents to let him go to Hogwarts instead, he knows he will be entering a world in which his aristocratic connections will be worthless. Indeed, the Malfoys, self-styled aristocrats of the wizarding world, will despise his Muggle ancestry, and even try to kill him. However, Justin is not asking for special treatment. While Draco is always boasting about his wealth and important connections, Justin never mentions money. Not only is it vulgar to refer to one’s own affluence, but money is not a subject that occupies Justin’s mind, because he really doesn’t believe that having Old Money makes him a more important person than someone who has newer money or less of it.

Justin’s prognosis is not very good. ‘Justin’ is a Latin name, indicating the ‘justice’ of this person’s character. However, I have a sneaking suspicion that he was named after St Justin Martyr (AD c100-165), a very polite gentleman who was murdered for refusing to abandon his convictions. The point of the surname ‘Finch-Fletchley’ may simply be that it’s double-barrelled, a sign of upper-crust ancestry. However, a ‘finch’ is a small bird, while ‘Fletchley’ (which I haven’t been able to find on any list of real surnames) literally means a ‘field of arrow-heads’. Here is a suggestion of a vulnerable person who will meet a violent death.
