More help please

[Scott Satterfield]

My ancestor is Anna Persdotter, born 1771.  You can see her in GID 26.1.8500 at the bottom of the page with her illegitimate son Gustaf.  I can't find her birth, however.  I looked at GID 26.39.41900, but there were 2 Annas born with fathers named Per.  Can anyone help me find her birth family?
 
Thank you.

Any new ideas?
 
Thanks and happy new year!
