Can you help solve a decades-old mystery???

I'm looking for the parents of my 3rd MGGF Henry Yates Conaway (from Delaware) who married a Sarah "Vautts" in 1843 - I can't find her parents because I can't figure out her last name. The jury is still out as to her maiden name - hard to decipher on the marriage certificate (attached). The only other Vautts that exist around that time are in AL and TX, and there is an AL Vautts/Vaults family that applied for Cherokee citizenship.

This line does have Indians in it (me being one of them), but it's not yet determined which person it was, Henry or Sarah, or both. Could Henry have been a Conoy and Sarah a Cherokee? Do you know??

I don't have photos of either one, but I do have one of their daughter Annie and her son Arthur, so please peruse my family tree and let me know if you know of these folks. Thanks in advance for your help!
