I gave birth to 2 sons, so I never got to use my girls names. Maybe one of them will strike you and your husband. The oldest would have been named after the Greek and Roman Goddesses of love: Venus (Aphrodite,Aphrodite was the Greek goddess of love and beauty. Aphrodite was the most beautiful of the goddesses.)
{Venus was the goddess of chastity in women. As Venus Genetrix, she was worshiped as the mother (by Anchises) of the hero Aeneas, the founder of the Roman people; as Venus Felix, the bringer of good fortune; as Venus Victrix, the bringer of victory; and as Venus Verticordia, the protector of feminine chastity. Venus is also a nature goddess, associated with the arrival of spring. She is the bringer of joy to gods and humans.}
And the 2nd son would have been Scarlett Victoria. Not quite as much history to go with this one. I am a big Gone with the Wind fan, so of course that tells you where Scarlett came from. But that movie is also where Victoria comes from, most people think Rhett and Scarlett's daughter was Bonnie, but there is a scene where Mamie tells Melonie that Scarlett is going to name the baby Eugenia Victoria. And Rhett only ever says that he is going to call her "Bonnie Blue"
Hope you find the perfect name for your child! I am sure you will. You may have to wait to see him or her to know what is exactly right. My youngest son was not given a middle name until 2 days after he was born. I knew he was to be William but I was torn betweeen middle names and waited to see him to decide.
