What is the origin of my surname, "Montingelli"?

[Meazzano]

Hi my surname is "Montingelli"...my grandfather comes from Cerignola, Apulia (Italy). All the "Montingelli" I know come from Cerignola or Andria, an other city in Apulia.

Do you know something about this surname, his origin in the centuries or something similar?

Thanks a lot.
