Cecilie Kirstine Nielsdatter (Munch) had a daughter, born in 1839,
out-of-wedlock; attempted to find them in the Klemensker census of
1840, and was not successful. They might possibly have left
Klemensker immediately after the christening; however, looked in the
"afgangslisten" (leaving list) for 1839, 40 and 41, with no results.
In the 1845 census her daughter, Cecilie Marie Wulf, is listed as
residing as foster-daughter with her mother's sister Englike
Margrethe Munch, and her husband Jørgen Peter Olsen of Allinge. In
