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.

Griffiths valuation was a land valuation carried out on behalf of the then government by Richard Griffiths who had previously carried out a boundary survey of Ireland for Ordinance Survey maps of Ireland (1825-44). The land valuation which began in 1848 was completed in 1868. The valuation of the county of Londonderry (relevant to Kilkie) was completed in 1859.

Whilst much of the 1831 census of Ireland was destroyed we are fortunate that most of the records for Londonderry survive. Family historian Bill McAfee has transcribed the records and provided internet access to these, for which we are grateful.
