Missing generations

Perhaps someone can give me a little direction. The earliest ancestor I have documented, Heinrich Ludolf Bartling, was born in Baumuhle and died in Dudensen.
Almost all the people in my family tree show Dudensen as original residence.
I have a copy of the 1689 census from Baumuhle that shows a Harmen Bartling and family. There is a Johan Heinrich Bartling born in 1680 who I suspect is the grandfather of Heinrich Ludolf Bartling as there is sixty four years between the birth year. I am searching for that missing link so I can tie these families together.
Any help or advice will be much appreciated.
