The record holds this spelling for boys and the name it looks like is a woman's. Diane and Dyana are unambiguously women's names in America; this one is not, and the difference of a single letter has apparently been enough to move it — which suggests it is not really a form of that name at all.

The story of Dyan
That is worth taking seriously rather than treating as a curiosity. When a spelling behaves in the record quite differently from the name it resembles, the usual explanation is that it is a different name arriving from somewhere else and being filed under the nearest familiar shape. Names from Arabic, Armenian and several South Asian languages have all been anglicized into forms that look like existing English names, and the giveaway is exactly this: a distribution that does not match. A page that assumed the resemblance would be reporting the wrong name entirely.

Not established
If the source is the Roman goddess's name the sense is about daylight, but the record's distribution argues against that route. Other origins are possible and none can be established from an American register.

Fashion outlook
Dyan sits outside the current charts, and that is its own kind of answer: naming cycles can only date the names they carried up. A name this rare has no decade stamped on it — it cannot go out of fashion, because it was never in.
