He was married to Sophia Hartfeil (she is German) m. nov 7, 1866 in Lafayette.
They had 5 children. Enno, was the start of my family in Lafayette, Indiana. I have records of his kids, and so on.. but I don't have much that connects him to his family back in the Netherlands.
His father is Jan Simons Aardappel (b. Abt. 1798, d. Abt. 1859). I don't know much more than that.
