Friederich Emertsens parents were Emert Mortensen [11173] (1688-9 Sep.1742) according to this tree (https://www.familysearch.org/tree/pedigree/landscape/24BS-5PX) and Birgitte Hansdatter [11174] (1691-1775).
Emert Mortensen had a son Peder Emertsen Dom. Quasimodog. = 20 Apr. 1732 (https://www.sa.dk/ao-soegesider/da/billedviser?bsid=349972#349972,69526052), and a son Jacob Emertsen 20 Trin. = 7 Nov. 1734 (https://www.sa.dk/ao-soegesider/da/billedviser?bsid=349972#349972,69526055). Margrethe Mortensdatter carried the child; she might be a sister to Emert Mortensen. One of the witnesses was Laurs Holst, who must be Morten Laursen Holsts father.
