Baby Name Poll

Cheney(chay-nee) is a family name used on all first borns in my family, both boys and girls. Everyone else(literally) have used it as a middle name for their children but my husband and I want to use it as a first name for our child. We are having a girl for our first and yes we are absolutely set on it as a first name! We aren't asking for opinions on the name itself, just the spelling. Should we stick with the original spelling Cheney or go with either Chaney or Chaynie? Chaney is my idea but my husband likes more unique spellings so he prefers Chaynie. I don't mind Chaynie but the logical thinker in me says Chaney would be better if we do change it. My compromise for it is Chainey though. Which spelling do you think would be better? ~Amanda
