tidbit's list "Master list Jamie" of 2 great name ideas: Tess - Vesper!

Master list Jamie

Cosy and warm but with plenty of substance and strength, Tess is a literary diminutive that works perfectly well as a stand-alone name. Stylish in the Netherlands, it currently sits outside the Top 1000 in the US, where Tessa and Teresa are currently preferred. 
 Perhaps the most iconic and memorable Tess is the heroine of Thomas Hardy's Tess of the D'Urbervilles, the moral center of the tragic novel. Typically derived from Theresa, the name is associated with harvest time, though it may also be used as a nickname sunny Welsh Tesni, aristocratic Contessa, and rare Otessa. 
 
The name ranked in the US and UK charts back in the 2000s and 2010s, but has since been displaced by longer form Tessa, but we could easily see it returning to the charts in coming years. Chosen by fashion writer Plum Sykes in 2010 and by actor Luke Macfarlane in 2023, other notable bearers include writer Tess Gerritsen and presenter Tess Daly. 
 
International alternatives include Swedish Tessan and Dutch Tessel.

Tess

This Latin word used for evening spiritual services was introduced to baby namers by the Eva Greene character Vesper Lynd in the modern James Bond film Casino Royale in 2006, based on the Ian Fleming novel, and is just now beginning to provoke interest among namers, with its spiritual reference and soft, whispery sound.
 On a more earthly note, the 'Vesper Martini' is the famous drink ordered by James Bond in both the book and the movie Casino Royale.
 A name likely to enter the Top 1000.
