Baby names: Noah enters top 10 for boys, Amelia remains top for girls per BBC News

This BBC report http://www.bbc.com/news/uk-37254187 starts thus:

'The name Noah has entered the top 10 most popular boys' names for the first time, while Amelia has remained the most popular for girls, the Office for National Statistics said.

The list of most popular baby names in England and Wales in 2015 also showed Oliver has remained top for boys.

The ONS said the results were "based on the exact spelling of the name given on the birth certificate".Grouping similarly-pronounced names would change the rankings, it added.'

Can you guess what grouping of names would take the top spot but that the BBC would rather keep quiet? Might it be Muhammad/Mohammed etc.?
