Maddysen is of American origin, a modern creation that gained popularity in the late 20th and early 21st centuries. It's a unisex name, though it's more commonly given to girls. The name Maddysen consists of two elements: 'Maddy', which is a familiar form of Madeline or Madeleine, and '-sen'. The '-sen' suffix is often associated with Scandinavian names like Jensen orelsen, but in this context, its origin is less clear as Maddysen is not a traditional Scandinavian name. Despite its unclear etymology, Maddysen has been embraced by many families seeking unique and modern-sounding names for their children. As of recent years, it appears in the Social Security Administration's baby name database, indicating its contemporary usage in the United States.
"The name Maddysen seems to have had some popularity, with a peak of seven babies named Maddysen born each year in both 2007 and 2008. However, the number of babies named Maddysen has been consistently low or negligible for most years since its initial appearance in 2000."
