Petrea Thornton was my Great-Great-Grandmother. She is buried in Ainsworth, NE. You can find this information on www.findagrave.com and request a photo. She was born Feb 12, 1853 and died Oct 1, 1921. I do not have any information on her parents. I believe her maiden name was Anderson but I can not verify this. Please let me know if you have any information you would like to share.
