For Christian families, a lot of activity can happen around Easter. One of these is baptisms. If you are lucky, there may be a listing of this in the family bible.
If you are even luckier, there may be a certificate of the person who was baptised, listing off their names, the name of their parents as well as other information.
Catholics may also have First Communion and Confirmation.
If your church, or your family has traditions such as these, you may also be able to write to your church for records.
Don't forget that the Easter holiday can be a source of records!
