Translation of "прапрадеда" in English

Это единственная фотография моего прапрадеда, которая у меня есть.

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

Моего отца, деда, прадеда и прапрадеда звали так же, как и меня.

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

Отец отца — это дед. Отец деда — это прадед. Отец прадеда — это прапрадед, а названия для предков прапрадеда не определены.

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.
