If you have a male ancestor born about 1840, strongly consider Civil War service. Children were often named for grandparents, both male and female. Frequently middle names or even a first name was the mother's grandmother's maiden name, especially if the name was related through several related families. We would like to repeat here, with her permission, her list of ways to preserve your family collection of papers and memorabelia, which she says came from the Internet.

Heat causes damage.
Don't hang valuable objects over radiators, heat-producing appliances or the fireplace. Books you want to read 20 years from now shouldn't be shelved on the mantle, the window sill or the radiator. Light causes fading and other damage. Don't put valuable books and paper where they'll get direct sun or bright light of any kind. Hallways or other rooms without windows are best.
