You made a mistake, Jacob Engle is the husband of Louisa Marie Probst, and the son of Clement Engle. I believe the Clement could be the son of Johan Peter Engel, Sr. of Frederick, Maryland. He is also a brother of Michael Engle/Ingle too. See http://www.familysearch.org
I am interested in your line, I would like to compare it to my Engle data base, could you send me a copy of it, preferable a GEDCOM file.
Also, I could send you a GEDCOM file too.
