Priceless family treasures

Recently, my sister Dorothy showed us a bunch of family "relics" that were in a box left by our mother, Hazel:

1. GG Grandma Clarrisa Crapo Davenport dress from 1900 or before. She was a very small lady.
2. Hazel Davenport Lewis wedding dress (green "flapper" style-1931)
3. Knit hat Dorothy wore as baby (about 1940)
4. A lock of my hair as a baby
5. A lock of hair and shoes Donald Lewis wore as a baby
6. Lock of Hazel Davenport Lewis hair (as a child?)
7. Bag for house slippers made and used by GG Grandma Martha Ann Townsend Lufkin (perhaps 1900 or before)
8. Small Native American doll belonging to Hazel Davenport Lewis as a child
9. Doll dress belonging to Hazel Davenport Lewis as a child

I hope family members might want to see and learn more about these articles. I wonder what should be done with them so that they are preserved and yet available to see?
