god, who knew I was a trend setter? 
loadsof those names were on our lists for ds, and some of them years ago for dd1 and dd2.
I love Astrid and Persephone (if ds had been a girl, there is a strong chance he would have been Persephone)
And Thursten/Torsten was very high on our list for quite a while. Dh wanted Octavius, and took quite a lot of persuading otherwise 
so we are clearly just ahead of the trend
