"Blend of Rhi and Lynn"
The name Rhilynn is commonly a female name.
Rhilynn is a modern American formation, first recorded in United States birth data in 2007. It joins an initial element, Rhi, to the suffix Lynn, the same pattern found in names such as Kaylynn and Raelynn. The first element does not correspond clearly to an established name with a documented meaning, so no meaning can be assigned to the name as a whole.
The pronunciation of Rhilynn is RYE-lin.
