Looking for:
I would love more on Katrine and Kresten. I have some branches of this part of my tree well-mapped, but these two are one of the brick walls on my tree. I'd love to know who their parents were (her father's name was obviously Ivar, and his Christen or Kresten), how many kids they had…where they lived in Denmark (possibly Vejle or nearby, as that is where the main branch of this family is from), anything, really.
