Marlowe
If you're very literate, this name maybe brings to mind to mind Christopher Marlowe or the lead character from Heart of Darkness. If not, this name probably just sounds like another soft -o sounding name in the trend of Harlow and and Shiloh and Willow. The difference is, unlike Willow, Marlowe has a masculine touch to it. It's classy and cool in one, but despite fitting in well with the name, your son won't have to worry about sharing it with any of his peers.
Marlowe is an English surname coming from the town of Marlow in Buckinghamshire. It is composed of the Old English elements mere meaning "lake" and lafe meaning "remnant; remains." It could have meant a place where a lake had been, or where a lake was perhaps drained.
