Hi !!!
I don't like the nn
Ollie.
First of all I think it is childish.
Second: I love the name
Holly so I don't like at all a name such
Ollie with a similar pronounce but so different.
However full names for
Ollie are
Olympia,
Olga and
Olena.
Because for
Olivia I prefer
Liv and for
Ophelia I prefer others.
Byeee
