You can avoid paying for ancestry.com fees, as many Peter Meyer records can be found at:www.familysearch.com
Once you find connections on that site, then you MIGHT want to join ancestry.
Personally, I'm a Norwegian genealogy nut, so I use ancestry.com daily! Yes, their databases contain errors, but you may find more clues about your Peter Meyer from Norway.
Advice: Always best to do your own research, rather than assuming others' ancestry.com trees are correct!
Lykke til! (Good luck!)
