I’m a Jane in my early thirties.
At primary school I was the only one, and my secondary school of about 1500 kids had only one other Jane (who coincidentally also shared my middle name!).
As a child I got a lot of ‘plain Jane who lives down a drain’ and I hated my name. I wanted a long name with lots of syllables so I could have a cool nickname. Jane doesn’t lend itself to diminutives or nicknames and I was desperate to have one.
As an adult I really like it. I’m usually the only Jane in a room. If I’m speaking to someone for work on the phone or email I feel like I get treated as though I’m older and more experienced than I really am. People seem to assume a Jane is in her 50s and knows what she’s talking about. I have a friend Janet, the same age as me, who has noticed the same thing. I do get called Jade quite a bit, when people aren’t listening properly.
I’d say Jane is a pretty good name to live with, but it wants a good nickname or a pretty middle name to give it a bit of a boost.
