One thing that I have found in being a member of Ancestry off and on over the years, is that it helps to know exactly what kind of information you are looking for. It helps lead you to what or how you would search for it.
If you have a specific family with that name in mind, you might need actual names and dates or places. If you are just looking for the name in general, that is what you will find.
For example. My husband’s last name is Scottish. His family is not Scottish. They had their Italian name changed at some point. If I google his last name, I would most likely find nothing of real value, but I would find that this last name comes from this part of the country or that, and perhaps that they originally came from X. Maybe some historical figures with that name, or family motto stuff.
So, you need to establish what it is you are searching for.
