I don't show a John Wilber ADRIAN but the Wilber middle name runs in a couple of David W's. With the marriage date of 1791, could he would be in the same generation as my John David Adrian, the first generation in US. I don't know anything about John David's siblings or cousins or even parents, only that he came to the US from Germany (Alsace). John David's line landed in South Carolina in late 1700's, settled in Georgia in early 1800's then to Alabama mid 1800's then to Texas after the Civil War. Do you have any more info to help clear it up?
