When registering
information from the book into the format of EDP
(electronic data processing), the following main rule
for choosing the family
name has been used:
Female individuals born before 1923 and male individuals born
before 1850 have been given
patronymic with
the addition of the name of the farm or place, or any
other name used as the family name whenever this was
known.
The family
tree is constantly updated. Check your relatives.
