The same lack of documentary evidence described elsewhere affected records of the 19th Century. No complete censuses or central records of BMD exist for Northern Ireland for this period. However, parish records, land valuations and tombstone records do Exist. In addition we have reached the period when family memories are written down or reliably passed down. Finally death records that do exist from the early 20th Century link back and give some credibility to the non-official records of the previous century.
