I suggested at the time we go down to the Town Hall and search though the records to fide out who the original owners were, maybe some information as to someone passing on in the house.
My Mother did not like that idea, she has been through some rather frightening haunting's and didn't want to take a chance that calling her by name may provoke her.
As time went on we did learn that our little ghost is a girl, the family has dubbed her Junior. We also quickly came to realize she wont do any harm or even try to frighten you. She has never been malicious only mischievous.
It wasn't to long ago I asked my Mother again if we might try to find out Junior's name, she still isn't up for it.
So the name Junior has stuck.
She seems not to mind being called that, and in fact if she has done something or taken something all we have to do is say out loud "Junior pleas don't do that or Pleas give it back I really need it".
