Thank you for your reply.
I wrote down Carl was born in Copenhagen from notes I made in the 1960s before my grand-mother died.
Carl married Ann Lawrence on 24/9/1873 in Camberwell, Surrey, England. On the marriage certificate his father was given as Christian Pedersen, Seaman (Danish Navy).
The story my grandmother, Lizzie, told me was he & his sister were orphaned young & were sent to live with an uncle on a farm. Carl was a seaman (Merchant Services).
His children were - George Charles, only one born England 13/1/1874 Annie Mathilda Arthur Sardinius Ada Louise* Elizabeth, my g-mother Henry William Alfred*
* died before 3 yo
Lizzie once showed me a beautifully written discharge paper from the captain of a ship where he served as 1st Mate (?) on a return trip to Japan. Unfortunately it's been lost.
He worked his way to Australia, eventually had a contracting business in Sydney but died on 7/5/1899.
