Boys firsts

Benno is a cool name in its own right -- there was a tenth century Saint Benno -- though it is also used as a lively nickname for Benjamin. Saint Benno of Meissen is the patron saint of anglers and weavers and, strangely enough, alliteration.
 Benno came to attention in the U.S. via the father and son duo of Benno Schmidt Sr. and Jr. Senior was the venture capitalist who invented the term venture capitalist and Junior was the president of Yale University. Benno is also the appellation of a student character in Umberto Eco's The Name of the Rose.

Crusoe, as in castaway hero Robinson, is a literary invention by author Daniel Defoe. In the novel, the character says his name is an Anglicization of the German Kreutznaer, which may be a place name or refer to a crossing of the river Nahe.

Short form Cru was given to over 100 boys in the US in a recent year, while Crue was chosen for around 440. Crusoe, however, has only ranked occaionally, most recently in 2021 when it was given to 10 boys.
