We came to the conclusion that Troy means trap, a hunting reference, though we hadn't come across Aberfeldy at the time. Troy seems to be cognate with 'true', rather oddly since the maze design of twisting, turning hidden lines implies trickery.
It may be related to cauldron, cf. Caerdroia ('City of Troy' or 'City of Turnings'), the final destination of the trapped bird or animal. Cauldrons, which are associated with witchcraft but also birth or rebirth, are tended and stirred by a hag. Tudor gardens laid out formal mazes with hedges as barriers as at Hampton Court. [Hag = hedge.]
Troy games are still played up north apparently according to

The folklore department of Åbo Akademi reported, as late as in 1985, that old people recalled that turf labyrinth games had been held secretly but regularly during bright summer nights: a girl would stand in the center of the labyrinth while a boy would try to reach her. If he could manage to reach her without taking any wrong turns, he should carry the girl out of the labyrinth the same way. If he was successful both ways, the girl belonged to him. The spectators would be singing and clapping their hands. An 80 year old woman remembered how the participants were sworn to secrecy and that there were many rules regarding symbolic objects and clothing, and that the outcome of the game was used to predict the joint future of the boy who had succeeded and of the girl who had waited in the center
Interesting about trolls, another hunting word (troll is the same word as trawl) applied to fishing with nets.
In 1979, a person from a fishing village in northern Sweden reported that it had been common to let the most beautiful girl in the village stand in the center of the labyrinth while the men tried to seize her or reach her first.[8] According to a 1934 report from another place in northern Sweden, it was believed that the labyrinth was the home of trolls, and that the trolls had taken a girl and kept her captive in the labyrinth.
The girl or bride suggests a bird though bride is a 'bright' word. It may be that bright light was also a way to entrap animals as with rabbit-hunting. In either case the sexual analogy is clear though Christianity managed to sanitise mazes turning the labyrinth into a spiritual package tour. Elizabethans, the ones in the sixteenth century at least, would have been well aware of the many linguistic word games. Come into the garden, Maud.
