I have come across a land abstract that has many names listed. I am NOT related. I will try to list as much as I can here, but may need to finish later. The property is in Berrien county, likely Benton Harbor area, and is referred to as Dunham Acres and seems to have a lot of Dunham family named.

There is more on the Dunhams going into the 1900's. Looks like the property got caught up in lawsuits. Hope something here can help someone.
