Great-great-grandfather

The father of a father is a grandfather, a grandfather's father is a great-grandfather, a great-grandfather's father is a great-great-grandfather, but no word has been decided upon for the generations before great-great-grandfather.

Tom's great-great-grandfather was a pirate.

My father, grandfather, great-grandfather and great-great-grandfather all had the same name as I have.

This is the only picture I have of my great-great-grandfather.

Tom's great-great-grandfather was a slave.

I knew also your great-great-grandfather.

It is the 15th of March of 2015, at a pizzeria on Lulu Island. Adil the Kazakh and I discuss the multilingual and multicultural landscape of South Asia, centuries ago, when there were many kingdoms in the region. Farsi was an elitist language, he says. His Kazakh is a Turkic language in Central Asia. I dutifully and gleefully inform him about PIE, Proto-Indo-European, the ancestral language of many Caucasoids today. The origin in theory is Southern Russia near the Black Sea, more than 6000 years ago. PIE was the great-great-grandfather of languages like Spanish, English, German, Welsh, Hindi, Greek, and many others today. Adil and I discuss about some modern humans who have genes from other species, like the Neanderthals and Denisovans. Scientists know that the brain size of the Neanderthal was bigger than the modern human's.

Tom's great-great-grandfather grew up in the same town as Mary's great-great-grandmother.

Sonny, I knew even your great-great-grandfather.
