Hi Judy, do you still want help with this family history? It's been a while, so maybe your research is complete.
If you are still looking, try posting in the Denmark forum (there are more helpers on that forum). In your query, include the information you already have. Also clarify what information you do NOT have but want.
Since you know that some of the children changed their surname and some did not, etc., it's clear you have found a lot of information already. No point in volunteers digging up stuff you already have. You'll attract more researchers if you clarify what you know and what you don't.
