What do we think of Nathaniel? Will people end up calling him Nat or can I steer them towards Nate if they insist on abbreviating?
Other options are
Alexander (nn Alex)
Sebastian (NOT to be abbreviated)
Edmund
Isaac
We'd like a Welsh middle name - current favourites are Owain, Llewelyn or Dylan.
Surname begins with R and DS1 is called Theo.
