I have mention of a Johann Ludwig Ache being one of three brothers arriving in the US in 1742. Another note states the brothers arrived 9/22/1752. (PA German Pioneers, Ralph Strassberger) All of the information I have was typed by someone so there could be a typo. Johannes Jacob and Hermannus are the other brothers. I don't have any information of his descendants though. I am descendant of one of the brothers.
