I'm able to access my free access account through family search but when in cannot access records I want to see, but and sent to where they want me to register for pay.
@McEuenVictoria4 According to your post, you are able to cross over from Family Search into Ancestry, but once there you can not open any thing, and you are seeing the offer to subscribe to Ancestry.
This suggests you are not in your Free Ancestry.com account.
After you cross over into Ancestry, look for you name in upper right, and click on tiny arrow at the end of you name. Then choose Account Settings. This will tell you if you are in a free account, or guest account.
If a Guest account you may try to log in with your free account user name and Password that you use for Ancestry. If you do not remember what those credentials are, you may need to contact Ancestry.com or call Family Search support 1 866 406 1830.
The free accounts do not give you access to everything in Ancestry. The owners of records in Ancestry can, and in many cases have, asked that their records be excluded from the free subscription. Many governments do not want Latter Day Saints getting free access to their records through Ancestry whilst making everyone else pay- this is both politically unpopular and considered to be illegal religious discrimination in many countries. For example in the United States, this would be a clear violation of the 1st Amendment of the Constitution.
The Church of Jesus Christ of Latter Day Saints and Ancestry.com have a partnership that is mutually beneficial. But as stated above, the free account does not give us access to everything in Ancestry.
Best wishes as you discover records of your ancestors.
