I have looked in my Kentucky 1850 census records and cannot find Alice Danforth nor Cyrus Talbot Bemis. There are several families of both names but none list the two people you are looking for. I did find A Cyrus T. Bemis in the 1850 Louisiana census. His age shows him born in 1830 in Ky.This might help in your search. Sorry I could not be of more help. Good luck.
