A great internet resource is Ancestry.com. They have some free databases as well as some you have to pay for. Just enter the surname you want to know more about, and you will be taken to a results screen that lists every record where that name was found. Again, many of them are free databases, but some require membership. Depending on the results you see there, you may want to consider membership. They do offer free trials that can be useful too.
