I have seen lots of posts concerning syncing FTM trees with ancestry.com online trees. I am wondering why people want their trees online. The reason I ask is this - in my research I have found trees online on ancestry.com that contain pieces of my and my brother's tree. When I find a tree, I send ancestry mail to the tree owner asking him/her to contact me so that we can compare our trees and exchange information. Most of the time I get no replies, and I have no idea why. I thought that the reason for putting a tree online was to elicit more information from people who see tree online. Do these people not trust me and think that I an on a phishing expedition? I do not know the tree authors, and they do not know me. But our trees have persons in common.
