Sketchbook owner's name?

[Ruskie]

There are only 4 Caitlins (with that spelling) in England in the 1851 census ... none of the surnames look like Car/l......etc

[Rosinish]

Equally, there's a family of Callinfords in Suffolk/Norfolk 1861 none named Caitlin/Catherine or similar

Lots all over England 1841/1851 with surname variants, not found a Caitlin or similar & need to go out now, hopefully someone will find something?

Assuming it's the signature of the owner of the book, a signature which has become more scrawly over the years (as they often do), my money's on Carlton Collingwood.

There were a few of them about at that time.

I'm hoping that the OP will return soon to give us some background to the sketchbook.

Thank you all so much for taking time to have a go at puzzling this out.  I hoped there might be a couple of responses, but never so many!   The book belongs to a family member and I don't have it with me.  We know nothing of its provenance. I remember there is only one watercolour, of Gibraltar seen from a named boat, and a pencil sketch of an unnamed village, the rest of the pages are blank.  I will make contact to get a photo of the written title of the watercolour with boat name, and post it here - I think it was dated 1853.
Again thanks for your helpful suggestions.

Can you also ask your family member where they found the book. It might give a clue as to where the person lived so we can try to locate him in the censuses.

Rootschatters love these kinds of puzzles so I'm not surprised so many have joined in to try to help you.

Catherine Williams to me

The more I look, the less I see 

If this is a name rather than a place name  I can only see 1 'dotted i'

The writing seems to be continual, no definite spacing i.e. is it a name & surname or a place name & dated when sketched
