Where does “Hancock” come from?

I can't write this etymology summary because the chain provided appears to be corrupted or circular—it repeats "English cocking" and "English ten" without progressing to older languages or establishing a meaningful etymology. A valid etymology requires a traceable path through different languages to an identifiable origin. Could you provide the correct etymological chain?
