Hello all,
Thank you for the helpful information and suggestions on possible origins, particularly on potential place names in Germany. Unfortunately I've not been in a position to move things on and discover any more about A C Kadansky since the original post in 2005. I plan to get back into research mode soon - after 18yrs, i'm hoping there is a lot more online (fingers crossed esp in Europe) than when I first started looking into this.
