According to the probate of the will of W.Jay Wilber 1914, son of Willis P Wilber, Hiram is the Brother of John, Vincent, Hazard Wilber. These are all Sons of Benjamin and Lucy (larkin) Wilber. As far as I know Lucy's first child was born in 1777, so 1804 is a stretch. Hiram went first to Wisconsin with Hazard and a sister Lucy Crowl. They all came from Rhode Island, then Madison County, NY then Dodge Co, Wi then Minnesota. Further generations ended up in California. Anyone have anything to add???
