Cynri

A name from ancient Welsh literature: in the poem The Gododdin, the three leaders of the ill-fated army were Cynon, Cynri and Cynrain. To that end, the name might have been invented for poetic effect, although there are several Welsh names ending in -ri, meaning "king". Alternatively, it may be a form of the Anglo-Saxon name Cyneric.

In any case, this could be an unusual name choice that's vaguely reminiscent of Henry, but it may prove burdensome to explain the pronunciation.

Pronounced KUN-ree.
