Elsie Pevehouse born/Kirksville MO 1886

My great grandmother was Elsie Pevehouse.She was born in 1886 in Kirksville, MO.I believe her father was Frank Pevehouse and that her mother's maiden name was Armstrong. I have information that suggests that her grandfather was William W. but I'm not sure where that info came from.Can anyone help me with Pevehouse's in Missouri?Keith L. Hamburger
