According to Irish legend, Saint Brendan the Voyager was the first European to touch American soil, and his name has been established here for decades, peaking in the late 1990s. 
 
Brendan first appeared on the US charts in 1941, especially popular, not surprisingly, for Irish-American boys. It is sometimes confused with the English surname name Brandon.
 Notable namesakes include Irish playwright Brendan Behan and actor Brendan Fraser. Mark Wahlberg used it for his son.

Brendan

In Celtic lore, Fergus was the ideal of manly courage, making it a charming, slightly quirky Scottish and Irish favorite.
 As a name, Fergus forms a link between Ireland and Scotland, as Gaelic tradition has it that Irish Prince Fergus Mac Eirc and his two brothers crossed the sea and founded the kingdom of Argyll in Scotland, thereby making this an excellent choice for parents of either country or those of combined heritage.
 Fergus has often popped up in children's literature, such as in Thomas the Tank Engine and Friends, and is the name of one of Shrek and Fiona's triplets. On a loftier level, there is the Yeats poem, Who Goes With Fergus? and Fergus MacIvor is a central character in Walter Scott's novel Waverley.
 With the nickname Fergie having been appropriated by two high-profile females, Gus might make a more approachable option these days.
