My information indicates that Frederick Isler born in 1842 and married to Mary Anna Elizabeth Norwood was the son of Michael B. Isler born May1,1811 in Georgia and died April 17,1901 in Ozark, Ala. He married Sarah Webb on October 20,1839. Michael was the son of John Isler,Jr. and Mary Bublin. I hope my information is accurate and helpful.
