I have hit a roadblock on John Burgess & Ann Morris of Delaware county, Indiana, "Approximate 1840s"

Do'es anyone have any info?

I am from a direct descendant of John & Ann Burgess. They were my 3rd Great Grandparents.

David Burgess & Elizabeth Bryan were my 2nd Great Grandparents

Joseph Burges & Elizabeth Moore were my grandparents

David Burgess & Elsie Pierce were my Parents.

I hit a brick wall with John & Ann.

Any info would be appreciated and will share what I have so far.
