Meaning bard, this is an original choice with poetic and melodic undertones. Bard itself has also come into consideration, both names bringing to mind Shakespeare and other literary lights. 
The Scottish surname Baird's most notable bearer was John Logie Baird, the Scottish engineer and inventor of the televisor, the world's first practical television system in 1926, and also the world's first fully electronic color TV tube two years later. Some might also remember puppeteers Bil and Cora Baird.

Casimir, a traditional name of Polish kings, could do quite well these days as we see the rise of Caspian, Cassius, Castiel, et. al. Like Leopold and Laszlo, Casimir is strong and worth considering if you've got an adventurous streak — and bet your son will too. An alternative commonly cited meaning that modern parents might prefer is "proclaimer of peace". The traditional Polish spelling of the name is Kazimir.

Ebenezer is the name of a biblical place --the stone set up by Samuel to mark his victory over the Philistines--rather than a person. It was adopted by the British Puritans as a first name and then exported to America, where it had some early popularity, even entering the Top 1000 in the 1880s.
 After appearing in Walter Scott's novel Waverly and Robert Louis Stevenson's Kidnapped, it made its most lasting impression as Dickens's miserly Ebenezer Scrooge, pretty much annihilating the name, but since Scrooge did reform at the end of A Christmas Carol, maybe there's some slight hope for the old name yet. If you have a sense of humor, you might consider it one of the darker <a href="https://nameberry.com/list/412/christmas-baby-names">Christmas baby names</a>.
 The good news: the appealing short form Eben--so if you find Ebenezer too loaded and quirky for your taste, you might skip straight to the nickname.
