Hi Anonymous poster SEG06,
Any newspaper could have a mention of Marie/Mary Schunemann Meyer if there was a local connection. I've indexed 4 of the German-American papers from 1903, but I haven't indexed family death notices or an obituary for that name (having a specific date would be more helpful).
I'd focus first on East Troy / Walworth Co. research collections. Maybe the local library has a clippings collection; or look for entries found through US Genweb?
