On researching my family Hartmann came across a great grand nephew of my great grandfather married Lula Dove Facer the nephews name was Emilius William John Hartmann.
I then found a family tree for the Facers which could answer your questions.
It was in 2001 I found it , if it is not on the net I could scan the pages and send it to you.
