I have a necklace that was my great-great grandmothers. It's a small 10K gold chain with a slide heart pendant. I wore it at my wedding.
I also have a ring that was my great-great grandfathers (from another side). He wore it when came to the U.S. My Dad has a revolver gun that was the first thing the same grandfather bought when he got to New York.
My third cousin actually has a key to the aforementioned grandfather's (and his wife's) mausoleum. It's been promised to me and my son....
