and His Father Jan Christoffel Horn.
This is what I was able to find in connection to Jan Christoffel Horn, in some time in History the family moved from Germany to Holland, it could of been because of the 30 year war.
What I have been trying to find is the names of the siblings of each of my 6th, 5th, and 4th great grand parents,
I'm trying to find the link with one Conrad Horn 1628-1704 he is my 8th great grandfather from another branch of my Family Tree. His daughter Maria Barbara Horn, her son Johann Nicolas Arnold, His son Johann Kilian Arnold, His daughter Catharina Margaretha Arnold, Her daughter Catharina Margaretha Barjollet, Her daughter Maria Catharina Scheick, Her daughter Gesina Raisig my Great grandmother Mother to my Opa Daniel Horn.....
