My gggrandfather ALFRED MARTIN HELVEY was on the 1880 census in Adair County , MO . The 1890 has no record of him ?His wife is on the 1880 census with him.But the 1890 census has her in Chariton County,Mo with their daughter and her husband . So I assume he is in Adair county in some old cemetery .But I can't find him ?Is there someone on this list that can help me ? Linda
