Our story of Lennis
Surnames were still optional in fifteenth-century Italy for people outside the great families, and the illegitimate son of a notary from a small town would not have had one. He was Leonardo, son of Piero, from Vinci, and each of those parts is a description rather than a name; catalogs that file him under V are following a convention that did not exist while he was alive. The same is true of a good many people from that period whose names look like surnames now. Meanwhile a similar-looking name has a completely separate origin: the Russian revolutionary took his working name from the river Lena in Siberia, where he had been in exile, and it has nothing to do with Leonard or with any of the names that resemble it.
Meaningscholars disagree
Lion strong
If the name is built on Leonard, the Germanic joins the borrowed Latin word for a lion to a word meaning brave or hardy. Whether this particular American name comes from there, from Lenny as a shortening of something else, or from nowhere in particular, cannot be established; the ending is an American addition either way and carries no sense.

LEN-iss
Two syllables with the stress at the front. The final s is unvoiced, as in miss rather than as in his, and the doubled n keeps the first vowel short.

Fashion outlook
Lennis 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
- Short, firm and easy to spell once heard, with no silent letters.
- Len and Lenny are two short forms in different registers.
- It works for a child of either sex, which the record confirms.
- The record carries this spelling for girls as well as boys, so it signals nothing on a form.
- It will be heard as Dennis and as Lenis, and both are closer to familiar words.
- The full name behind it cannot be recovered, so there is no meaning to give.
Nobody names a baby alone.
