"Blend of De- and Quincy"
The name Dequincy is commonly a male name from the "American" origin.
Dequincy is a modern American formation that attaches the prefix De- to the given name Quincy. The De- element is a familiar opening in twentieth-century American names such as DeShawn and DeAndre, and Quincy is an English surname, ultimately a Norman place name, that has also been used as a first name. The earliest United States birth record for Dequincy in the data is 1964, which fits this recent, formed-on-American-soil pattern rather than an inherited traditional name.
The pronunciation of Dequincy is de-KWIN-zee.
