Muggenburg, Mueggenburg, Meggenburg, Muggenborg, Miggenburg Muggenberg

My ggggrandmother's name was spelled Muggenburg in her Will, but her brother
spelled the name Mueggenburg...we have noticed relatives, i.e., brothers,
cousins, aunts and uncles have also used the other spellings as well. Can
you tell me the meaning of the name. How is the name spelled in Germany...Mu
and/or Mue?
Thank you.
