The history of my family, from Domesday Book to Housing Bubble, is recorded on several crinkly sheets of ancient vellum foolscap bound with human skin, which is sadly disfigured by an inelegant tattoo proclaiming: "Archibald Loves Doris Forever."
Apparently there was once a collection of ferrotype photographs, too, but these were long ago consigned to the smelting flames of self-censorship by some anonymous and hopefully distant relative.
Luckily, we also have a tradition of oral history. Family archives of the eighteenth and nineteenth centuries, for example, have been passed down from generation to generation as lines of heroic verse, in similar fashion to how the events of Homer's Iliad were remembered before writing, except there are more battles and Trojan horses in our chronology.
My favorite story details the murder of old Aunt Egberta in twelve stanzas of blood-soaked rhyming couplets. According to the poet, probably my Great-Great-Great Grandfather Rufus, old Aunt Egberta mistook an ignoble savage for a noble one, and was bludgeoned to death by a tribal totem. No-one was ever prosecuted for this ghastly crime, but it is whispered in the final stanza that Cousin Elba did serve a short custodial sentence for laughing during the post-mortem.
I would reproduce these entertaining verses here, but alas they were copyrighted by my sister's brother-in-law about three years ago.
