"Blend of Shae and Lynn"
The name Shaelynn is commonly a female name from the "American" origin.
Shaelynn is a modern American formation built from Shae, a common spelling of Shay or Shea, plus the suffix -lynn, which recurs in twentieth-century American girls' names such as Kaylynn and Raelynn. It first appears in United States birth records in 1985, and the records we hold show no earlier documented use of the name.
The pronunciation of Shaelynn is SHAY-lin.
