I'm seeking a death or burial notice for Mechtunda Baumgartner, born 1803 in Baden and died after 1880. She was the wife of Ursus Victor Baumgartner born 1780, and they lived in Germantown. He is buried in the St. Boniface Cemetery there, but she is not. She lived her last years with her daughter and son-in-law Francis and Caroline Noll in Kewaskum, or St. MIchaels. Since they are buried at St. Michael's cemetery, it's possible that she is also buried there. Are the burial records for that cemetery available anywhere?
