A Mr. Harwood had two daughters by his first wife, the eldest of whom was married to John Coshick; this Coshick had a daughter by his first wife, whom old Harwood married, and by her he had a son; therefore, John Coshick’s second wife could say as follows:–

My father is my son, and I’m my mother’s mother;
My sister is my daughter, and I’m grandmother to my brother.

— Charles Carroll Bombaugh, Gleanings From the Harvest-Fields of Literature, 1869
