Elestren

Less known than other Cornish beauties like Elowen, Demelza, and Kerensa, Elestren is a pretty botanical name ripe for wider usage. While it may have a starry, celestial feel, likely owning to sound-alikes Estelle, Celeste, and Seren, Elestren actually comes from the Cornish name for the iris flower, most specifically, the yellow iris.

Though it has yet to appear in the UK stats, it may still catch on (even if it is only quietly) among those looking for rare alternatives to Elowen.

Pronounced el-ES-tren.
