Kenneth, to get confirmation of the type you seek, it's necessary to know what type of DNA test have you taken, and with which company?
To get good linkage back that far, a deep-Y test is required; autosomal would be really washed out.
On the other hand, I know your line well, but that's not what you were asking.
I'm a descendant of Reitz-123 3 ways, have done ftDNA Y-700, and got a good match to a 7th generation Reitz descendant of Johan Friedrich, Reitz-433. That validates the paper trail through both clans, even though Reitz-123 and Reitz-433 were not brothers. The common ancestor is farther back.
