The name Elke is of German origin, meaning 'all, every'. It's a unisex name that gained popularity during the mid-20th century. In German-speaking countries, it's often used for both boys and girls, though it's more commonly associated with females in other parts of the world.
"Elke's popularity as a baby name peaked in the late 1960s with a high of 76 births in 1968, but it has since declined steadily, with only 7 births recorded in 2021."
