History & Origin

Sydna is best understood as a feminine form of Sidney, whose root is an English place name meaning 'wide island' or 'broad meadow by the water.' The name is scarce enough that this reading is the likeliest rather than a documented certainty.

It was never common, given to only about fifteen girls a year at its peak around 1940, with records reaching into the early twentieth century. A girl named Sydna then would belong to a great-grandparent's generation today.

Did you know? Softening a place-name surname into a girl's name with an -a was a quiet early-century habit, and Sydna reads as one such experiment on the Sidney sound.
