According to everything we have found, it all points to her being born in Italy. It may be difficult to find where they actually came from as their POB in Italy on the 1911 is just given as unknown. The only thing I can think of is to get her death certificate and see if that gives an actual place of birth. However, as I said in a previous post, it depends whether the person who registered the death knew that, if not it may just say Italy. Or, as she had obviously been in Cumbria since a baby, they may have assumed she was born there as well.
