Recognisable but not pedestrian either. Nice strong sounds. One of the best 'typos' ever.
I'd expect an
Imogen to have sibs with names like:
Violet,
Harry,
Harriet,
Stella,
Scarlett,
Lily,
Matilda and
Hugo. Looking at birth announcements with Imogens, I've seen all these alongside.
Yes, I've run into a few. One had a brother,
Henry. Another had one sister
Scarlett, that I know of. She was an older
Imogen. In her early teens.
I remember first hearing this name when I was 13. My mathematics teacher used it on his new daughter. I thought it was beyond ugly at the time and it's grown on me.
