Genealogy on my mother’s side shows relations to the storied court of Queen Elizabeth I in Shakespeare’s England and the current cast of “Game of Thrones.” “Games of Thrones” star Kit Harington (Jon Snow, King in the North) is a multiple great-grandson of Sir John Harington (1560-1612) a godson to Queen Elizabeth I and a member of her court. Sir John is also one of my multiple great-grandfathers. I hereby give a shout-out to Cousin Kit.
Sir John invented the first flush toilet and is why some folks call the toilet “the John.” However, I care more about his literary accomplishments. For example, in 1615 he published a book, “Epigrams Both Pleasant and Serious.” This included the noted: “On Treason – Treason doth never prosper, what’s the reason For it to prosper, none dare call it treason.” He also wrote the saying “Love me, love my dog,” which comes from a poem Sir John wrote for my ninth great-grandmother seeking to apologize for striking her little dog. He is better known for his translation of Ludovico Ariosto’s (1474-1533) “Orlando Furioso.”
Before I dwell too much on my relationship to Sir John; I do wonder what he and I really do share, genetically speaking. (My own expertise in genetics arose from research I did related to cigarette smoking.) DNA; Sir John and me Genetic tests were among the hottest gifts of 2017 and 2018. They may scratch much the same intellectual itch as genealogy, but with a sometimes misleading sheen of scientific surety.
On average each person shares about 25% of their DNA with each grandparent. My third great-grandmother; Polly Harrington (1804-1856), is my most recent Harington by name. On average we would likely share given the imperfect nature of these predictions about 3.13% of our DNA. By the fifth great-grandparents; 128 ancestors have contributed to an individual’s DNA, causing each person’s share to drop below 1 percent (0.78%).
Estimates of inheritance from ancestors depend on the model used. By one model, I share an average of only 0.049 percent of DNA with my 2,048 ninth great-grandparents. But if this were not little enough to call nothing, another genetic model shows a 50-50 chance of the shared DNA being nothing. Nevertheless; I will cling to my assumed inheritance of 0.049 percent from Sir John.
Descendants can guess playfully which ancestor gave them a particular trait. Sir John is the only writer I know of in my family. So, perhaps I owe to him a speck of credit for my literary accomplishments, like my book of short fiction. My genetic work and my writing even collided in a dramatic monologue “The DNA Bank: Expressing the Risks for Purposes of Informed Consent;” which was published online in the now defunct HMS Beagle. This monologue was translated into Icelandic and performed on Icelandic State Radio in December 1998 to mark the passage of landmark legislation for genetic testing on the Icelandic population.
