I see you posted this back in 2004. Did you learn more about Mary A Spice? I'm researching John Spice, who was married to Polly A Spice and Polly is a nickname for Mary. A real hint though is that living with them is Elza Deckard, age 14. If this is new to you, check out the 1900 Washington, Green, Indiana census Page 260A. If you have any info on John Spice, I'd love to know!
