"Variant of Hazel"
The name Hazely is commonly a female name from the "English" origin.
Hazely is a modern American variant of Hazel, the English name of the hazel tree, recorded in Old English as hasel. It adds a -ly ending of the kind that appears in American girls' names coined in the late twentieth and early twenty-first centuries, which makes it a distinct form rather than a straight respelling of Hazel. It is not an older spelling of Hazel: it appears in United States birth records only from 2010.
Hazel means "The hazel tree".
The pronunciation of Hazely is HAYZ-lee.
