There is no connection, known to the people of Snape, North Yorkshire between ourselves, Harry Potter, Professor Severus Snape or anyone else in that fictional world, there is no Spinners End and we are nearly 70 miles (as the crow flies) from Hadrian's Wall. We do not believe JK Rowling ever visited the village.
Just outside of Snape on the road to Bedale is a small hill' known locally as Kings Kell. It is rumoured that Henry VIII fell off his horse there whilst courting Catherine Parr. It is almost certain that he never came to Snape, but why spoil a good story! Kell in Norse/Old English means spring and there is certainly a beck there. One of the 3 pubs in Snape was at that junction.
Derivation of the name Snape
There are two villages in England called Snape, the other one is in Suffolk. It is of note that our Snape sits on the edge of what was a large marshy area known as Snape Mires. The Mires are now drained and farmed but are still susceptible to flooding. The village is linear in layout and has two lanes that lead down to the Mires. The following is extracted from the most excellent website about Snape in Suffolk (see link) giving a convincing derivation for the name Snape based on geographical features.

This little straggling village, among the marshes and fields, must have had a beginning, so I thought I would try to find it; and this is what I found: Snape, Snapes, Snapys- are three different ways of spelling the word which, in the Anglo-Saxon language,
Snape meant bog or marsh or winter pasture, according to Ernest Weekley. It is chiefly a scatterment of cottages and small farms lying along the marshy river bed and, beside the lanes leading inland. Reference to Dr. Ernest Weekley, a renowned linguist and etymologist (1865-1954) can be found on a number of internet sites, including takeourword.com/glossary.html
To confuse the issue, from the Online Entymology Dictionary we have "snape" an old english verb meaning "to be hard upon, rebuke, snub," c.1300. This is from the Old Norse word sneypa "to outrage, dishonour, disgrace.
