1330+ Boy Names That End in Y

Kacy as a masculine name represents a modern usage of what has traditionally been a unisex or feminine name. It likely derived as a variant spelling of Casey, which originated from an Irish surname meaning 'vigilant' or 'watchful.' The spelling variation with a 'K' gives the name a more contemporary feel. While Casey has been used for both boys and girls, Kacy for males is considerably less common. The name peaked in popularity in the 1980s and 1990s but remains relatively uncommon for boys. Kacy has a friendly, approachable sound with its short, two-syllable structure, and the 'y' ending maintains a youthful quality that can transition well into adulthood.

Gilley is a masculine name with Anglo-Saxon roots, deriving from the Old English personal name 'Gyllic' or possibly from 'gill,' meaning 'ravine' or 'narrow valley.' The name may also be connected to the Scottish and Irish surname Gilley, which comes from the Gaelic 'Mac Giolla,' meaning 'son of the servant or devotee.' As a first name, Gilley maintains a folksy, rustic charm that evokes rural American heritage. While never among the most popular names, Gilley saw modest use in the southern United States, particularly in the mid-20th century. The name gained some recognition through country music singer Mickey Gilley, though it remains relatively uncommon as a given name today.

Thery is an uncommon masculine name with multiple possible origins. It may be a variant of Terry (itself a diminutive of Terence or Theodoric), or could derive from the Old Germanic name Theodoric, meaning "ruler of the people." In some contexts, it might also represent a surname that has transitioned to first-name usage. Thery has remained extremely rare throughout history, never appearing on popularity charts in most countries. Its brevity and distinctive pronunciation give it a modern feel despite its potentially ancient roots. The name's rarity makes it appealing to parents seeking a short, strong-sounding name that's unlikely to be shared with others in their child's peer group.

Sergay is a masculine name that represents a variation of Sergei or Sergey, which ultimately derives from the Latin name Sergius. The name has Slavic roots, particularly popular in Russian and Eastern European cultures. Historically, it was associated with a Roman family name and later became well-known through various saints and notable figures. While the more common spelling is Sergey in Russian contexts, the Sergay variant offers a slightly different phonetic interpretation. The name carries connotations of respect and honor across cultures where it's used. Though less common than other variants, Sergay maintains the strong, classic appeal of its related forms while offering a distinctive spelling alternative.
