Onslowe

A rare surname name that could follow in the footsteps of Harlow, Marlowe, Winslow et al., Onslowe comes from the Old English name Andrǣd, which likely relates to Andrew and Anders. In turn, this could give it the more figurative meaning of "the manly one's hill".

This spelling has never appeared in the US stats, and while alternative form Onslow featured once back in 1917, parents may well be put off this name if they read it as "on slow" or hear it as "onslaught.

Pronounced ONZ-lo.
