My great-grandfather is Henry GASSMANN born 1861 in Switzerland. He & his family came to Bond & Clinton & Madison Counties in Illinois in 1873. Henry married Louisa ABLITZ (b 1867 IL) in Bond County on 3 Nov 1887. They had a son Adolph Henry GASSMAN in 1888. Twelve years later the 1900 US Census show Henry as a widower. We can find no information as to the fate of Louisa Ablitz Gassmann. Can anyone help?
