Michael Hartwig, a farmer, his wife Julianna, and daughters (Katharina, age 24; Anna, age 22; Maria, age 19; Magdalena, age 15) arrived from Lübeck at the port of Oranienbaum on 4 July 1766 aboard the English frigate Love & Unity under the command of Skipper Thomas Fairfax. Arriving with them in Oranienbaum were two additional children: (1) Stephan [Gottfried] Hartwig, his wife Elisabeth, and daughter Anna (age 1); and (2) Anna [Hartwig] and her husband Konrad Götz, and daughter Susanna (age 1).
