I have a problem with Sarah E Keisel buried in Manti City Cemetery. She looks like the Sarah I am looking for, but her married name should be Murdock. Unless she dropped the Murdock name after 1910 or married another Keisel after 1910. Does anyone have access to obits or other records that could help?

Below are my sources. I may have 2 different Sarahs, but the 1910 census is the Sarah I'm looking for. Thanks for any help!!!
