Maybe because October ends with the Day of the Dead!
Anyway, how about a challenge for Family History Month?
I challenge you to help someone else with their family history work.
You could help someone get their family tree on FamilySearch, or help someone sign up for the FamilySearch partner sites. You could take an hour to help someone search for records about their ancestors or add records you've found about your ancestors as sources on your public family trees to help other researchers.
If you feel like you don't know enough about family history work to help someone else, you're just plain wrong. If you can log on to a website, you can help someone with family history work. When you offer someone help with family history work, they're not expecting the leading expert in the field. It's okay if you don't know something, or even if you don't know more than the person you're helping. Sometimes people just need someone to talk to while they do it or to tell them that they're doing well. You can be that person.
Helping someone with family history will help you too. The best way to learn is to teach!
What are you going to do for this challenge?
