Close enough! I believe it to be Emma KEEN. I must confess that I do have other evidence. This is some of the rest of the family.
James Keen was my gx3 grandfather, Eliza Keen nee Osborn my gx3 grandmother and Richard Keen my gx2 grandfather.
I just wanted to check whether anyone without any preconceived notions could come up with a 'K' for the initial letter.
Emma's grandmother was Sarah Osborn. This census is the only direct link I have to her being Eliza's mother.
