EleanorWoofed7's list "Solid and strong girl names" of 3 great name ideas: Lucasta - Susanna!

Solid and strong girl names

Lucasta was invented by seventeenth century poet Richard Lovelace for a collection of poems dedicated to a lover named Lucy, and is familiar through the Eugene O'Neill play and film Anna Lucasta. Lucasta is a distinctive, rarely used choice and a logical extension of the Luke/Luc/Luca names.

Lucasta

A pretty and plausible Latin name that's gotten a bad rap through the years via a link to Lucrezia Borgia, who, though long considered a demon poisoner, was actually a patron of learning and the arts.
 Lucretia is a U.S. First Lady name, borne by the wife of President James A. Garfield; a worthy namesake is Lucretia Mott, a Quaker abolitionist, and peace and women's rights advocate.
 In the Harry Potter saga, Lucretia Black Prewett is a pure-blood witch.

Lucretia

Susanna is an old and under-appreciated name, perhaps because of the recent overpopularity of Susan, that is certainly due for a comeback. 
 
The Susannah spelling is just as appropriate as Susanna. The two versions seem to have traded places over time as the dominant version. Neither spelling is in the Top 1000 at the moment, though we expect that will change over the next few years as more modern parents rediscover these beautiful Biblical names.
 
How is Susanna different from Susannah? The h-less version feels a bit more streamlined and modern, and might refer more directly to an ancestor named Ann or Anna. Susannah seems more old-school Biblical and more self-contained, while Susanna resembles a smoosh name: Sue + Anna. But Susanna and Susannah are pronounced the same and are equally beautiful.
 
A European short form of Susanna that's become popular: Sanna or Sanne.
