Hallo Andrew,
please ecuse me for my bad english, i write from germany. I think, your ancestors named schoengarth are from breslau, silesia, germany before 3. Worldwar. (now its name ist wroclaw in poland) the first of my ancestors who went to america was SCHÖNGARTH, Carl, * Breslau, Schlesien (Wroclaw, Poland) ca. 1814. he came to America at 6. Dec 1869 with wife and many children. some sons came after the war in silesica also to wisconsin (grant, clark county), his son William went 1871 to america. more you see in my ancestry or in the german site: www.gedbas.de or you mail me to breslau@online.de. I have the most ancestors until schoengarth gottlieb, died 1807 in Breslau. I would like to hear from you.
