The story of Wm
English clerks abbreviated the commonest names as a matter of course, and the conventions were fixed and universally understood: Wm for William, Jno for John, Thos for Thomas, Chas for Charles, Robt for Robert. They are all over parish registers, census returns, gravestones and business letters, and nobody reading them was in any doubt. What happened next is a records problem rather than a naming one. A clerk copying from an abbreviated source into a form that wanted a given name wrote what was in front of him, and the abbreviation entered the count as though it were a name. The same thing produced Jno and Chas in the record.
Meaning
resolute protector
The name being abbreviated joins two Germanic elements, a word for will or desire and a word for a helmet. The contraction itself carries no meaning; it is a piece of handwriting.

Fashion outlook
Wm 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.

The trade-off
- It stands for one of the most-used names in European history, with forms in every language.
- The short forms of that name are among the most established in English.
- It is an abbreviation, and a person carrying it will spend a lifetime explaining that.
- Entries under this spelling are clerical artifacts rather than choices, so it is not safe to assume anyone was called it.
- The spelling is recorded for girls as well as boys, which is a further sign of how it got into the record.
Nobody names a baby alone.
