I believe that Kaadekildehus is a place in Denmark not a name.
In sogn Orte in Herred Baag in amt Odense in denmark you find a place called Kaadekildehus.
9 januar 1881 was born a boy Jørgen Rasmussen in Kaadekildehus. He was the son of Knud Rasmussen and Maren Margrethe Mikkelsen.
So this sounds more like a place. Maybe it is the place where your ancestors lived at one time in history.
If you could give some more info like birthdates, marriage and death dates in denmark then it would be easier to help.
