Hi.
I`m making maps and some time ago i realised that there are hardly to no maps of 2nd level administrative divisions of Danube principalities. I decided to choose 1774 specifically because of Moldova census and Bucovina still being a part of Moldova. I have run into a lack of sources problem (obviously because there are actually hardly any sources, for Wallachia). So i have a question, can i use census data of following years for administrative borders? If not, why, and if yes, which year/years specifically? And what can i use for Oltenia? Can i use austrian censuses? (if such censuses still exist. I havent researched this topic yet)
Thanks.
