Building My Family Tree

Hi,

I am trying to build my family tree and I might be able to go as far as the early 1800 and I came upon this site that has several books on the Gould family.
"http://www.ancestralbooks.com/SurnamesG.html"
I checked them out on the web, it seems that nobody so far had nothing bad to say about them. I would like to buy from them but they are new and they have the free searchable CD-ROM promotion going, so it is kind of interesting. Anyone knows about this site, just write me a line. Thank you.
