Elfego is an uncommon given name of Spanish origin, derived from the German name Adalbert. It means "noble and bright." The name gained some recognition in history through Elfego Baca, a New Mexico lawman known for his bravery and skill during the Lincoln County War in the late 19th century.
"Elfego has seen a fluctuating trend in birth numbers over the years, with peaks in 1959 and 2000, and several periods of lower activity, particularly between the late 1980s to mid-1990s and then again from 1997 to 2013. However, there has been a recent resurgence since 2014."
