Marlon

Could be a combination of 'moor' and 'land', meaning "from open grass or marsh land".

Marlon pronounced MAR-lon. English in origin or possibly (Old French) "little hawk", and/or may be a variation of Merlin. Popularized by actor Marlon Brando in the modern day.
- a boy's name (also used as girl's name Marlon)

Marlon may find its origins in the Old French word, "merlin", meaning, "little hawk", or is possibly a variant of, Marcellus, which is the root name for, "Marc", as cited in the BTN listing. But it should be noted that "Marlon" and "Merlin" do not share their roots with "Marlin", which is short for "marlinspike", a sailor's tool.
