Robyn

Although it is not common in the US, it has been very common in New Zealand. In the 1950's and 60's it was in the top ten and the male version Robin was also quite high. Two of the teachers were called Robyn at the school I used to go to.

The name Robyn was given to 250 girls born in the US in 2015.

The name Robyn was given to 177 baby girls born in he US in 2012.

Robyn isn't as modern as we tend to think. There are records of a several men, from different areas of England, named Robyn Hode, along with Robin Hood and Robyn Hode.

It is not entirely a feminine spelling. The male singer Robyn Hitchcock spells his name this way. I used to think that it was only a stage name, but no, this would seem to be his real name.

Just to back up what Pippin said, the birth index for 1953 shows up his name, albeit written as 'Robyn R Hitchcock.' Looking at records from 1966 to 1995, I can estimate that there are about several dozen male Robyn's born in that period. From the ONS list that goes back to 1996, there are still less than 3 to around 6 male Robyn's being born in any given year.

In that respect, I would say that Robyn is just a variant of Robin, not a feminine variant of it.

Going back to the comment I made on February 17th, I have since found out that, according to Kneen, Robyn is (or maybe was) used in the Isle of Man as a diminutive of Robert. However, seeing as if, in the 'Robyn (given name)' page, there are 3 male Robyns listed there, one British, one Canadian (born in Brazil to Canadian parents) and one American, I feel as if these two origins should be separate, unless, of course, there is evidence that the usage of Robyn as a masculine name may have spread from the Isle of Man.

Robyn is also the Czech form.
