Baby Name Poll

Oliver and Evander have been my husband and I's favorite names since we've started discussing having kids, but now that our little man is about to be here we can't decide which we want to use, and we don't like how the sound together. We've had some difficulties getting pregnant so we are worried that this will be our only child so we don't really want to wait to use the other for a next baby that may never happen. But we were rewatching Harry Potter and fell in love with Olivander/Ollivander (which is the surname of a fairly minor character if anyone is unaware) and we really think it could work for us, it combines the sounds we love most about both the names and we just think it sounds really handsome and sophisticated? Do you think it can work as a first name or is too weird? Also which spelling do you prefer? Ollivander is the spelling from Harry Potter but I think we like Olivander just a smidge more? Thanks for your thoughts!
