The name Marlow has its origins in the Old English language, derived from the elements "mere" meaning a lake or a pool, and "hlaw" meaning a hill or a mound. It was originally a surname, referring to someone who lived near a hill by a lake or pool. The name gained popularity as a given name in the 16th century.

Marlow is believed to have been first used as a place name in England, referring to the town of Marlow in Buckinghamshire. The town's name is thought to have been derived from the Old English words "mere" and "hlaw," suggesting its location near a hill by a lake or pool.

One of the earliest recorded uses of Marlow as a given name dates back to the late 16th century. Christopher Marlowe, the renowned English playwright and poet, was born in 1564 in Canterbury, England. He is best known for his plays such as "The Tragical History of Dr. Faustus" and "Tamburlaine the Great."

In the 18th century, Marlow gained popularity as a given name, particularly among English aristocracy. One notable bearer of the name was Marlow Sydney, the 1st Earl of Romney, who lived from 1766 to 1840 and served as a British politician and army officer.

Another famous bearer of the name Marlow was the English explorer and writer Marlow Moss, who lived from 1828 to 1904. He is best known for his travels in central Africa and his book "Through Atolls and Islands in the Great South Sea."

In the 20th century, Marlow continued to be used as a given name, although less commonly than in previous centuries. One notable bearer was Marlow Thomas, an American film and television actor who lived from 1924 to 2012 and appeared in numerous popular shows such as "The Twilight Zone" and "Star Trek."

While the name Marlow has its roots in Old English and has been used for centuries, it has remained a relatively uncommon given name, particularly in modern times. Its rich history and connection to literary figures and explorers have contributed to its enduring appeal and significance.
