<<But the person with the surname Eames at the bottom of the page is female. Looking at the 1851 census for the same family her name is Frances.>>
Oh dear, more haste, less speed, sorry... I saw Frances at first but then decided the 'Daur' wasn't the same as the ones above...I see now there is a a very faint curve to the D - and it doesn't look much like Son written way above.
So the initial letter of the unknown word is probably F.
