On a web news >from Romania I read about a project between University
Babes-Bolyai >from Cluj-Napoca Romania and Norwegian Historical Data
Center of University >from Tromso called "Historical Population
Database of Transylvania 1850-1914" released in April-May 2017. It
contains "twelve selected micro zones incorporate as a sample covering
almost 7% of the historical population of Transylvania, making
possible a long- and medium-term research".

The database is open and searchable (English and Romanian).

This "micro database" contains transcriptions >from civil registers
(births, marriages, deaths)for only a few places in Transylvania and I
don't know if it will be continued and enlarged. Anyway it is worth to
try it.
