Nellie
NEL-ee
A sweet English nickname-name that usually comes from Helen or Ellen, carrying the sense of light or brightness.
Meaning
Nellie is generally a familiar form of Ellen, and sometimes of Helen. In the excerpted 19th-century source, Helen is linked with meanings such as “a lamp” or “a torch,” and another proposed Celtic explanation is mentioned, though not confirmed. In practice, Nellie has long functioned as a baptismal pet form rather than an independent original name.

Fun fact
