Many thanks for all the info on Niels Ditlev's siblings, very much appreciated. Unfortunately Church Book image(Anna Marie's marriage) didn't come through.
I have a big gap to fill now from when Ditlev was confirmed(14 yrs old) up until he arrived in Australia in 1874. It has been said that he probably would have been "in service" so therefore registered on the Draft Register. Have tried several websites but no success so far - not even as to when he left Denmark & where he went to from there.
Family "story" has it that - 1) Ditlev as a young man once danced with Royalty.
2) Ditlev arrived in Aust as a sailor after being shipwrecked on an island for 3 months before arriving in Aust.
FACT or FICTION - who knows??
Once again thanks for your help!
