FamilySearch has probably the best search capability of any of the websites where you might find pedigrees.
The collection has expanded well beyond family trees. So, when you are at the site, you should look for other records as well.
Your best bet is to search using as much information as you have. If you get too few responses this way, first remove the mother's last name. Her name is the one most likely to be entered incorrectly in a family tree. the father's name of the ancestor. If you still get too few responses, omit the spouse's name and use only the father's name with the ancestor's name.
See the definition of terms for any questions on the meaning of the entries.
