My dd is 13 and ds 10 and, as it turns out, have two of the most popular names you can imagine for children of their age! I don't know how we managed that because they were not particularly common names when they were born, but 5 years on and they were surrounded by children with the same names at school
.
Dh and I have incredibly common names too, I am sure top 5 for the years we were born.
Anyway, if I were to have a baby this month I think I would name a girl Zinnia or Susannah and a boy Jonathan.
