Ancestry Charts

It is difficult for me to find the information I receive from ancestry.com RW because I can not pay hundreds of dollars for the international database and not a local genealogy library. How do I trust these maps? It seems that people have tons of information, but I'm not seeing any census or anything to save.

Precisely, if the person who submitted this information has documents to prove what they are posting not.
I try to find at least some form of documentation for all my entires some I can not, I must admit, but most I do. Remember that it is only an idea without the documentation, first contact the person who submitted the information and see if they have records they may have posted not only names and records of researchers some do not. And as it is in search of his person to check the work. Anyway hope this helps and good luck, and good research

I am happy to see someone who is alert.
NO file anywhere ... in LDS files, ancestry, or any other secondary source is guaranteed. They are not guaranteed to be wrong, either. One way to check is to recover files for a name, and see that in many cases, there is conflicting information. That tells you right away that at least one is incorrect (and perhaps both).
The Internet has opened doors incredible, but it also opened people to take the "easy", without understanding the pitfalls. I can not answer on international files, but also to American research, you can use www.usgenweb.com as a place to locate sites of county basis, which often have posted more original sources. Not all are great sites .. some are a little more pages of requests.
The best you can do is to contact the author, after comparing what is offered. Even without contact, you may be able to zoom in on the town, and independently verify the level of online sources (such as census extracts will, land records, etc..) I also like the review of genforum positions where I can find those related to my question. You'll quickly identify those who use primary sources, assessment, or simply what they can catch someone else. Click on the name of the poster, and whatever other investigation, they may have posted.
I'd rather have 5 names in my "file" and know to be true, that the names of 5 trillion.

Some are more reliable than others. Half are above the average half worse.
(This is the nature of the medium, not an attack on half of those who downloaded GEDCOMS.)

Click on the box "has sources" or "Is notes" or both. If the source of someone is another WFT GEDCOM or a CD, take it with a grain of salt. If the primary sources and notes are transcriptions of these sources, the author would have done it, but chances are it is legitimate.

Look for Dixwell Ketcham, for example, and follow his ancestors TUTHILL since 3 generations in my database. This line is above average. Not all my data is also good. I wish it were.

Your LDS FHC or a public library may have a subscription census images. Feel free to communicate.

You can always write to the person, unless the header says "Do not write", and request sources.

Use the information as clues not as fact. For example, I live in Texas and my parents were born here. However, my ancestors lived at the time in Virginia, North Carolina, South Carolina, Missouri, Georgia, Alabama. But I would not know exactly where in those States. If I had not already found my family before I can use Internet sites as an index of writing documents.

You may notice some people have different information about the same person. However, sometimes you will see a full page of the same information the same diff.
