What can you tell me about Montemarcone Basso, Avigliano?

[montclaire]

I have a family status certificate (Certificato di Stato di Famiglia Storico) on the way from Italy, and I have been tipped off that the address listed is in Montemarcone Basso, Avigliano. I have not had much success googling Montemarcone, as American sites tend to lump it all together as Avigliano. Is there anything to know about this specific section of the region? I will have the exact address in a day or two, I will probably also be posting the certificate for translation.
Thanks in advance

and here is another...
Alto and Basso - obviously at the top and the bottom of the hill on which the village is built.

>MONTEMARCONE ALTO<

If you scroll down on this one there are some video's that they 'say' are of/about Montemarcone!

As you can see here - neither are very big...

Doesn't seem to be too much there, judging by the satellite images. Has the population of Avigliano decreased substantially since the early 1900s?
