"... Anna Margaretha SCHMIDT b: 1781 in Germany ..."

According to the death notices the family published for her in Milwaukee's German lnaguage press (at least 3 different papers), she may have been born c. 1789...? But birth years are also notoriously variable in reportage provided by family members. This family group you've posted is pretty well represented among the 150± Killian and Kilian entries or references found in the most current version of "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950) / an ongoing, independent project created, compiled and edited by Gary R. Rebholz. Related surnames include Fueldner Füldner Gensler Riedel Orth Bilo Beck Bohn Simon Stiller Michel Ley Richert Hoffmann.
