We chose a name that fit our criteria of travels well, easy to spell, no negative connotations (there were lots of names I liked but when I looked into the origin it was pretty unpleasant) and outside the top 100.
Didn't realise till we told a midwife her name it was a character in a tv show we didn't watch. Its now shot up, and will probably be the name we don't want - as in, flash in the pan associated with a particular era. But, there are worse things.
Currently trying to name no 2 and failing to come up with anything at all.
Something I think people miss: my daughter's nursery class have so many names that are basically the same sound. So think: Ella, Anna, Ava, Aria, Isla, Nova, Cora. Genuinely, there are about two girls whose names don't fit that format, and actually I'm more upset by how 'generic' her name sounds against that than the fact there might be two of them.
I actually think the 1980s where yes, there was more than one in each class, but Sarah / Helen/ Kate/ Claire/ Rebecca / Jessica all at least sounded different, even if they had an initial tagged on to the end.
Also agree about the workplace and the cumulative popularity over time: I once worked with 5 Katherines, born across about 30 years, all with different spellings.
