The story of Marlo
Marlow sits on the Thames and its name records drained marshland; Christopher Marlowe, Shakespeare's contemporary, carried the surname. Marlo entered American given-name use for both sexes in the twentieth century, and an actress of the name from the 1960s carried the feminine use. It is in current use.
Meaning
remains of a lake
From the Old English mere, 'lake' or 'pool', and laf, 'remnant' or 'leavings' — ground left after standing water has gone. Marlow in Buckinghamshire preserves it. The construction is unusual for an English place name and the reading is documented.
