Hi Sandy G,
The Azorean Government digitized their records and they are housed on a government web site, called Centro do Conhecimento dos Acores, but we just call it the CCA. It's in Portuguese. Luckily, someone created a navigation site for the CCA and it's in English. It's Tombo.pt. The English version is here:
The navigation is in the left pane. You can scroll down, click on Azores, then the island (Pico or Sao Jorge), the the council, then the freguesia (village). Or just type the freguesia in the search box at the top of the left column.
There is no Ribeira on Pico. There's a Ribeiras, so you want to type that into the search box. You have Norte Grande spelled correctly.
You'll also want to cross reference with the Azores GenWeb to see what indices exist (if any) for your freguesias:
http://www.worldgenweb.org/azrwgw/ Point at: Maps, Database, Indexes. Then you'll need this to learn to bumble your way through the Portuguese. The documents follow a format:
Good luck,
