Why is "Leeds" plural? Why not "Leed"? Any others?

With apologies to Douglas Adams and John Lloyd:

BECCLES (pl. n.)
The small bone buttons placed in bacon sandwiches by unemployed guerrilla dentists.

BURTON COGGLES (pl. n.)
A bunch of keys found in a drawer whose purpose has long been forgotten, and which can therefore now be used only for dropping down people's backs as a cure for nose-bleeds.

GALASHIELS (pl.n.)
A form of particularly long sparse sideburns which are part of the mandatory uniform of British Rail guards.

HASTINGS (pl.n.)
Things said on the spur of the moment to explain to someone who comes into a room unexpectedly precisely what it is you are doing.

It isn't plural

The name "Leeds" came from "Leodis", which was a name recorded in Anglo-Saxon sources for a Celtic kingdom that survived in the area for a while after the Anglo-Saxon invasion.

Leeds was an agricultural market town in the Middle Ages, and received its first charter in 1207. In the Tudor period Leeds was mainly a merchant town manufacturing woollen cloths and trading with Europe via the Humber estuary. At one point nearly half of England's total export passed through Leeds. The city's industrial growth was catalysed by the introduction of the Leeds and Liverpool Canal in 1816 and the railway in 1848. The name &quot;Leeds&quot; came from &quot;Leodis&quot;, which was a name recorded in Anglo-Saxon sources for a Celtic kingdom that survived in the area for a while after the Anglo-Saxon invasion</p>
