Baby Name Poll

My husband and I recently came across this name on an Australian YouTuber, Lannan Eacott. Supposedly it's originally the Irish surname O'Leannain just anglicized. Upon further research it can be spelled Lannan or Lannin. Basically it is pronounced like Landon without the D. We really love this for our baby boy. But cannot decide which spelling looks better. We also need some less common but still traditional middle names that will go well with it. He has a big sister named Juno Beatrice who is 16-months old. Lannan/Lannin itself is set in stone for his first name. The only thing we are debating about it is the spelling. Thanks. ~Bridgett
