Unless you have documentation on these extra children of David and Agnes Preisch, then they should be removed. Heinrich Preisch is my 6th great grandfather, and his will was probated in 1797, so date of death is also WRONG. My group, Descendants of Heinrich Preisch, have also implemented two markers at the old Peaked Mountain Cemetery. One for Heinrich and his wife (which clearly shows the right years of baptism and death), and one for Augustine and his wife. If you are managing my ancestor, the information needs to be corrected.
