Joseph D. Ibbotson wrote this, a recollection of information told to him:

When grandfather Dunscomb went abroad with his family, living in Halle and later in Nurnberg, he left his business in the charge of a partner whom he completely trusted. He never mentioned the name of this man who absconded with all the cash he could lay his hands on.
My uncle, Henry Ibbotson, and my great-uncle, Thomas Darling (Yale, 1836) both told me the story of grandfather's meeting with his creditors after the failure. They knew him as a man of integrity and offered to settle for a fraction of the indebtedness - about twenty-five cents on the dollar; but grandfather refused. "A dollar is a dollar, and I shall pay in full." This he eventually did.
