"Blend of Shari and Lynn"
The name Sharilyn is commonly a female name from the "English" origin.
Sharilyn is formed from Shari, a short form of Sharon, and Lynn, a name element common in English feminine names. The combined form first appears in United States birth records in 1934, which is consistent with a modern blend rather than an inherited name.
The pronunciation of Sharilyn is SHAR-uh-lin.
