Lake or waterfall; flaxen-haired
Lynniah is a modern American elaboration of Lynn or Linnea. It likely draws from the Welsh word 'llyn' meaning lake, or the Scandinavian name Linnea, which refers to the twinflower named after botanist Carl Linnaeus. The suffix '-iah' is a contemporary stylistic addition to create a more melodic, multi-syllabic sound.
