I haven't looked at the original register, but I have a printed transcript dating from 1900 (copies are probably also available online). Hubbercoe appears in this, as does Hubbercove - no doubt both are variants of the same name.
Googling for Hubbercove and Yorkshire produces some suggestions that it might be in the Skirethorns or Threshfield area, but I've pored over a large scale map for that part of the parish and didn't spot it.
