"Blend of La- and Troy"
The name Latroy is commonly a male name from the "American" origin.
Latroy is a modern American formation built from the prefix La- plus the name Troy, the same pattern found in names such as LaShawn and Latrice. The name first appears in US birth records in 1966, which points to a twentieth-century coinage rather than a name inherited from an older language tradition. It carries no meaning beyond the elements it is made of.
The pronunciation of Latroy is luh-TROY.
