The story of Trinidy
The word does not appear in the New Testament. A Latin writer of the third century put it together out of the word for three, and the councils of the following centuries spent an enormous amount of argument, politics and occasional violence working out what it was supposed to describe — with the decisive wording hammered out at meetings whose minutes survive and make for uncomfortable reading. It is one of the clearest cases of a word being made to hold a position rather than to report one. As a name it has been given in the English-speaking world since the Puritans, who liked doctrines for daughters.
Meaning
Threeness
The Latin word trinitas was built to mean a group of three, and it was invented for theological use — the concept needed a word and the word was made for it. The respelling here changes the ending and nothing else.

Fashion outlook
Trinidy 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.
