Maddielynn is an uncommon and unique given name of modern origin. It combines elements from two well-known names, Madison and Elizabeth, by blending their sounds together to create a new, harmonious name. Maddielynn can be seen as a unisex name, though it's more often used for females. Its usage began in the late 20th century, making it a relatively recent addition to the naming landscape. The name Maddielynn does not have any specific meaning or association attached to it, aside from its component parts - Madison (meaning "son of Matthew") and Elizabeth ("God is my oath"). This allows for personal interpretation and attribution of meaning by those who choose this name for their child.
"Maddielynn's popularity appears to have surged initially in the mid-2000s, peaking at a decade-high of 10 births in 2016 before leveling off with consistent years ranging between 5 and 7 births since then."
