"Blend of De and Shane"
The name Deshane is commonly a male name from the "American" origin.
Deshane is a modern American formation built from the prefix De-, which appears in a large group of coined United States names such as DeShawn and DeWayne, combined with the name Shane, an English form of the Irish Seán. The pattern matches the name's first appearance in United States birth records in 1968 rather than any older linguistic root. It is best treated as a coined American name rather than as an inherited traditional one.
The pronunciation of Deshane is duh-SHAYN.
