Hi Bryan: I believe your John Zull was the son of George Zull & Eve Albright. Eve died in Seneca Co.,OH. Not sure where George died.
John had a brother Adam, twin brothers Andrew & George and a sister named Eve. I don't have the details in front of me. Going from memory. My wife is descended from George Zull. George moved to Michigan where he died.
If I contacted you before, sorry for the repitition.
Do you have a photo of John? All the brothers served in the Civil War.Seems as though John moved to Eastern or North Eastern Indiana. Don't recall the county, but think it was on the Ohio boarder.
We have the Albright/Albrecht family back to the 1400's.
