Emmely is of German origin, derived from the Germanic elements " heim" meaning "home" and "mag" meaning "strength". It was likely created as a female form of Emmerich, which means "home ruler". The name gained popularity in the 19th century, particularly in Germany. Today, it's still used but not as commonly as some other names of German origin.
"Emmely saw its peak popularity with 30 births in 2007, but has since declined, with only 6 births in both 2020 and 2023."
