Dara

"swarthy"
An old Irish surname that was big in the 1960s, but would be an unexpected choice for a child now.
Dara
Irish, Persian, Punjabi, Khmer
"oak tree, fruitful; wealthy; leader; star"

"from the deer estate"
Spirited and bubbly, but handsome and preppy too, Darby is a surname style choice that fits in well with the likes of Alby and Lennox. Derived ultimately from Old Norse, as a surname, it likely…
