Help them

There are many people who are looking for any shred of evidence concerning their ancestors or relatives. For example, a person's family book may talk about his/her ancestors getting married in Ireland, but there are no records confirming that information. One way that you can give to others today is to index family history records. When you index records, you are providing a way for people to find the sources/records that verify others' ancestors' lives. And a bonus to the joy that comes from giving is that you come upon interesting names and stories.
