Keira and Edmund are expecting their third baby -- a brother for Cecilia and Wilfred.
Keira writes: "Current names on my list are Otto, Rafferty, Ludo and Theodore. My husband likes Augustus and Hercules. We both quite like Laurence but don’t love it, and I like Laurie but not Larry as a nickname.

Cecilia and Wilfred are so swoon-worthy. I can see why you want another name just as good. I also think it's great that you are willing to push the boat out a bit for this baby as it opens up a whole world of exciting name choices.
All the names suggested below are saints names.
Alban - Alban is the anglicised form of the Latin name Albanus meaning "of Alba Longa" (the ancient Italian city). Three saints have borne the name; the most famous was the British soldier martyred in the 3rd century for whom St Albans is named. His name is often thought to derive from the Latin name Albanus but, as legend has it that he was a Romano-British native, it is likely to derive from the Celtic *albiyo "world".
Atticus – A Roman name meaning "from Attica" (putting it in the company of Sebastian, Luke, Adrian and Laurence and the like which all derive from ancient places). It has been borne by saints, a philosopher and the notable literary character.
Augustine – The anglicised form of Augustinus, a derivative of Augustus. Its medieval usage was inspired by Saint Augustine of Hippo and Saint Augustine of Canterbury.
Barnaby – Saint Barnabas was an early disciple of St Paul. Barnaby is the English form of the name and Barnaby was historically commonly used in places with churches dedicated to the saint.
Finnian – Perky Irish Finnian belonged to a whole host of saints. It derives from the Old Irish find meaning "white, bright, blessed".
Ignatius – Stately Roman Ignatius is a great saintly choice with plenty of style. It has plenty of nickname options, including Iggy, Gus, Nash or Nate.
Inigo – Saint Ignatius of Loyola was born Íñigo -- possibly a form of Ignatius itself, or else a Basque name meaning "my little one". Renowned architect Inigo Jones is a famous bearer, also.
Leander – A strong, heroic Greek name meaning "lion of men" which can be shortened to Leo, Lander, Anders etc.
Magnus – A great (if you'll excuse the name pun) Latin name which has been borne by emperors, kings and saints.
Malachy – An Anglicised form of either Máel Sechnaill -- "disciple of St Sechnall" (ultimately derived from Latin Secundus "second") -- or Máel Máedóc -- "disciple of St Madoc" (ultimately derived from Aed "fire"). Malachy itself was also borne by a saint.
Nathaniel / Nathanael – St Nathanael is an alternate name for the apostle St Barthlomew with the great meaning of "God has given."
Nicander – The Latin form of the Greek Nikandros meaning "victory of man" -- pulling together elements (and sounds) found in Nicholas and Alexander. It was borne by 2nd-century BC Greek poet, a Spartan king and six saints.
Octavius – The original name of Emperor Augustus with just as much gravitas. As in Disney's Cinderella, I'm a fan of Gus as a nickname for Octavius, but Ovie, Oggy, Tavi and more are options.
Peregrine – Peregrine is a Latin name meaning "traveller" and borne by five saints. It is also the name of a falcon. Pip, Perry and Reggie could be used as a diminutive.
Quentin – Deriving from the Roman name Quintus, Quentin has a decidedly suave style.
Raphael – Famously borne by an archangel but also borne by saints (as both Raphael and Rafael). Raffy, Ralph or Rafe could be used as short forms.
Silas – Derived from the Latin name Silvanus: the name of the Roman god of the forest. Silas appears in the New Testament for a companion of Paul who is considered a saint.
Sylvester – From the Roman name Silvester meaning "forest", borne by several saints and popes.
Thaddeus – Often shortened to Tad (though you could also use Ted/Teddy), Thaddeus is a Biblical saint's name with various appealing meanings.
Thorfinn – A striking Scandinavian name -- not uncommon in the Shetland islands -- which was borne by a 13th century saint.
Update: Welcome Barnaby Augustus!
