Suzanne,
The above marriage is on page 629. And if you search (Ctrl+F) in that book for "Manuel Furtado Salvador" you'll see all the marriages from his sons. Reversely, you can search for his parents, and slowly build your entire Flores+Corvo tree just from this book alone. You should then use the book and the CCA site to verify your data, but as a Flores researcher myself, I can tell you this book is worth every penny even if it's price was 3x the $18. Even if you don't have a Kindle device, you can install the Kindle software just about anywhere and use that to read the book.
At some point, when you have it up to the mid-1700s, I'm sure we'll find common ancestry between you and my wife (and my children).
