According to The Scotsman, 1841 census records for Scotland were placed online, along with many other historical Scottish documents.
The announcement by ScotlandsPeople, a leading genealogy website, is a major advance for people researching their Scottish family history.
Documents detailing births, marriages, occupations and deaths can now be accessed online along with more than 50 million other Scottish records.
One of the hand-written documents from 1759 shows the record of Robert Burns’s birth in Alloway, Ayrshire, on 25 January.
These original 1841 records have never been seen online.
The unveiling today of the material online is part of a five-year project that is funded by the Scottish Executive.
It contains the most comprehensive online set of family history information for any country in the world and is one of the largest single information resources on the web.
