It is difficult for the leaves to find "difficult" people. I've tried the leaves quite a bit so that I am familiar with them and can reasonably answer questions about them. The leaves do make easy things easier to find. I'm not certain they are that helpful in other cases.
This pedigree chart comes from my Ancestry.com tree on my paternal grandmother, Ida Trautvetter Neill. There are leaves everywhere--most of them are from online trees and other extremely secondary sources that are not the focus of my research. It's pretty easy for Ancestry.com to match with people I've already located quite a bit on. That's the case with everyone on this tree except:
- Erasmus and Mary (Gross) Trautvetter
- Benjamin Butler
