Hi,

I am new to Ancestry.com and have lots to learn.
In order to create a family tree does one need to buy "Family Tree Maker" to create the tree and then upload it to Ancestry.com or can the tree be created in Ancestry.com directly?
Secondly I see a few public family trees that have members of my family. I don't personaly know the author. Can I use that tree as a starting point and somehow build upon it and save it with my own family name?

Thanks,
Mark
