Aspen is the English name of a tree whose leaves are hung on flattened stalks, so that they turn and shiver in air too slight to move anything else — the quaking aspen. The word itself is old: Old English æspe, with cousins across the Germanic languages. Two syllables, both easy, and a spelling almost no one has to be told twice.

From æspe (Old English) to Aspen
The story of Aspen
The root is Old English æspe, related to German Espe, Dutch esp and Norse ösp, all naming the same restless-leaved poplar. In Middle English the tree was the asp, and 'aspen' described things belonging to it; by the later medieval period the adjective had taken over as the noun, which is the form English kept. Aspen groves gave their name to the Colorado silver town in the 1880s, and that town later became better known than the tree to most Americans. The given name arrives out of both at once — the word and the place — and belongs to the broader American habit of naming children after trees and landscapes.
Meaning
aspen tree — the trembling poplar
Curiously, the -en was once an adjective ending: an 'aspen leaf' meant a leaf of the asp tree. The adjective swallowed the noun, and aspen became the tree's own name.

The Adalberto test
Every popular name lives one long story — a climb, a peak, a slow settling back. Aspen's later chapters haven't been written yet, so we borrowed them: Adalberto climbed just as high around 1981, and its whole arc is on record. Line the two peaks up, and Adalberto's path sketches the road Aspen is walking now.

The trade-off
- Spelled the way the ordinary English word is spelled, so it is written correctly by most people on the first hearing.
- Used for both boys and girls with the same spelling and the same pronunciation, with no separate form to choose between.
- Two short syllables that survive being called across a playground and fit easily in front of most surnames.
- Sits within a well-established family of American tree and landscape names, so it is understood as a name straight away.
- For most Americans the first association is the Colorado ski town rather than the tree, which brings a whiff of money and holidays with it. Strongest in Colorado and its neighbors, where the place-name reading is nearly automatic.
- The great majority of Aspens are girls. A boy will meet forms, teachers and strangers who assume otherwise on paper — manageable, but worth expecting.
- The obvious shortenings are awkward: Asp is a venomous snake, and Aspie is widely used as informal shorthand for Asperger's. Ace and Pen do the job better.
- This name's whole wave is recent, so nearly everyone carrying it is young. There are no elderly Aspens to make it sound established — that comes with time.
