It is sometimes explained as a variant of the English surname Harlow, which comes from place names meaning “army hill” or “stone hill”, but this is a suggestion rather than a proven line. The name was in use in the United States in the 19th century and is familiar from the folk singer Arlo Guthrie. Its short, open sound has carried it well beyond its unclear beginnings.
The name Arlo in numerology
An Arlo is usually the first to say yes to a new idea, tends to decide quickly and likes to be responsible for his own choices.
A 1, R 9, L 3, O 6 give 19; 1 plus 9 is 10, then 1. He prefers a clear goal to a long discussion.
The vowels A and O total 7, a quieter layer. Behind the quick manner is a mind that wants to understand, to check, to think in peace. R and L make 12, then 3, so in action he is sociable and expressive and handles obstacles with humour and conversation.
His first letter and first vowel are the A again, a 1. People meet a direct, self-assured Arlo whose reaction to anything unplanned is to go straight forward.
Drive, reflection and charm form a lively mix, in a name of four letters that sketches only an outline. Others may see in him a person who acts while others deliberate, and who is happy to admit a mistake and start again.
