Do you know who Joseph Hardy Rideout married, or the name of your friend's great-grandfather (you wrote that Joseph was his brother)? Do you know where these folks lived? Any of their children's names? These things might help someone else recognize your guy. I looked my files, and in a book a lot of people use, called "Rideouts in America," and I don't see a Joseph Hardy, but there are some Josephs with no middle names, with birthdates a bit off from what you suggest. If you're at the beginning of your search, try <>. Don't type in the middle name. They have a lot of Rideouts in there, but don't believe everything you read. Sometimes people are hooked up without enough checking. I hope this helps. Good luck!
