Clevette/Clevett is not a common name in England so it shouldn't be too difficult to try and find your Clevette family. I am also researching the Clevetts and have extracted all the info from the IGI, Vital Records of the British Isles and 1881 census. They are all set out in their families now. I haven't been doing this line for long so my data is fairly limited at present.
To help identify your family - do you know the names of Charles & Alice's other children and do you know where Charles came from? I do have a Charles Clevett born 1876 Angmering, Sussex, England.
If you would like more details on the Charles or can provide more info, I'll be happy to provide you with any details I have.
