I search any information on the painter/artist Carl Johannes Mück and his family - wife Nielsine nee Schmidt and children Hans Max Emil, Maren Emilie, Max Johannes, Gerda, Lauritz and Signe Emma Gerda. The children were born in Haderslev, Denmark between 1895-1903. Hans Max Emil was born 1894 in Lucerne, Schweiz.
The family moved from Haderslev, Denmark to Hamburg around 1905.
Carl Johannes Mück was born in Haderslev 1866, and the wife was born on the Danish island Brandsoe 1865.
Any information on the family or on his paintings is of great interest.
I also search contact to people, who are in posession of some of his paintings. He signed his pictures "J. Mück"
