Overseas research I have found the overseas stuff on Ancestry is limited and it is hard to verify if the record is actually your ancestor if they have a common name. There are better ways to do overseas Research.
I usually google the country and "genealogy" to get advice on what to do online.
The Mormons have tried to every record that can be found. Go to your local LDS church and they usually have a genealogy library where you can check a database and then order records on film or fiche. It arrives in about 2 weeks.
Also Check out Cyndi's List of Genealogy sites. She has sites listed by country.
Jon is there anything that you want me to check out at Ancestry. I currently have a full world membership.
