Carla: I have just completed an article on Hans Jacob Koger based on research of county court order books and other primary sources. I found no evidence that Peter Coger was his son, tho' some might not agree with my conclusions.In any event, I did learn much about Hans Jacob that was not known; for example: the court ordered his son John to take posession of Jacob's estate for the care of his father. Jacob died in November of 1782, not June of 1783 as previously believed. I have copies of those records. I also have survey records and maps of the land patented to Jacob in Henry Co., VA. The article has 59 footnotes of documentation. I'd be happy to send you a copy at no charge.
