It is very difficult to go further back in history, mostly for two reasons: on the one hand, the great war and the plague played havoc among the local people and, on the other hand, a lot of printed materials were also destroyed, including church documents which were kept more consistently only during the Swedish era and which are the main sources of genealogical information.
Sellest piirist on raske kaugemale ajaloo sügavustesse minna kahel põhjusel: suur sõda ja katk olid teinud kohutavat laastamistööd inimeste hulgas ja hävis ka kirjasõna, sh suur osa Rootsi ajal järjekindlamalt pidama hakatud kirikumeetrikatest, mis on põhilisteks genealoogilise informatsiooni allikateks.
