With Liam at the top of the boys' popularity list, parents might discover the still-rare Niam. This is one of the unknown but plausible boy names starting with N.

Too tied to those well-publicized twins.

The short, cute Pim is a Top 100 boys' name in The Netherlands though little-known outside that country. But in a family overrun with Williams, Pim could make an original nickname setting a modern child apart from father Will and grandpa Bill.

Quinn is an engaging Celtic surname that is still on the rise for girls but beginning to flag for boys. As a female name, Quinn is in the Top 100, used for over 3000 baby girls last year, but toward the bottom of the Top 500 for boys, given to 700 baby boys.

Ryan’s use as a given name was inspired by the surname Ryan, a variation of the Irish O’Riain meaning "son of Rían."

Straightforward and down-to-earth, Sam is the name of the son of the co-stars of The Americans, Keri Russell and Matthew Rhys.

Sounds like the name of a new synthetic fabric.
