Barry, Nigel, Godfrey (what would he get called for short? God?), Sheila, Tracey, Lesley. They are all parent and grandparent names though, so were clearly used for babies once upon a time.
I know brothers (one primary school age, the other a toddler) called Antony and Ian, and slightly older sisters Nora and Agnes. Some of those names sound very old-fashioned to my ears, but it's only a matter of time before they all come round again. I also know a little Mary, which makes a refreshing change from all the Bea, Bella, Ella, Emily, Amelie, Amelia, Evie kind of names.
When my DD was a baby (she's now a teenager), another mum at a baby group introduced her newborn DD as Ada. I thought it sounded SO frumpy at the time, but actually it does seem to fit in with the similar Evas and Avas, as well as the other 'granny' names like Agatha and Edith which have come back into fashion.
