I just looked up births for Aeres, as I've never seen it before as a name, and there were quite a few of them - mostly after 1900, almost every single one in Carmarthenshire. (I've just been on holiday round there! Strange coincidence.) It means 'heiress'. Interesting! I would imagine an awful lot of people think her name is
Iris, it sounds so similar.
Every single one of those English names is in my own family, too, & I'm from North Wales :)
