This person is my great great grandfather and I believe was born in France, then moved to London and married a lady named Clara in 1841 with whom he had Julia, Clementine, Louisa and Albert.
He is listed as a toymaker and this tallies with our verbal family history that our relations were French toymakers.
I am aware that this board is for 'Canard' but I was told that this was the original spelling of the name.
I have also been told that this line goes back to the Canard-Duchene champagne house.
Thanks for any information and contact me if you would like access to Abraham/Adolph/Adolphe/Adolphus and my tree.
