I think its impossible to be original nowadays unless you opt for names from 20 or 30 years ago. No-one calls their children Susan or David or Jane or John now do they?
But there are thousands named Ruby, Dorothy, Matilda, Frank, Henry, Harry, George - all names our parents mostly wouldn't have considered for us!
Sorry Hatrick, but I know several Theas, Saskias, and even two Kittys.
My dcs have incredibly common names for their era, as do me and DH. I am close friends with two other women with the same name as me. There are at least five people on my phone with the same name as DH. I know 5 Claires and 5 Kates.
Its just the way it is.
