Where does “Keswick” come from?

I cannot write this sentence because the chain provided does not support an etymology for Keswick. The chain only gives "Old English ċȳse" without indicating how it connects to Keswick, what ċȳse means, or what languages precede it in the derivation. I would need a complete etymological chain showing the sound changes and semantic development from the oldest form through to Keswick to write an accurate summary sentence.
