I'm just starting out with info from Mom, & she doesn't know much. How can I find info about my great-grandmother, Mary W Altheide. All I know so far is that she was from Streator,IL and married my great-grandfather, David K Agnew. My Grandfather, David R Agnew, was born in 1898 in Erie, Pa, and attended military school in Quincy, Il. He spent summers in Streator with the Altheide family, who owned a clothing store. Sound familiar to anyone? Thanks, Barb
