I see that the 1880 US Census for Town 99 (Hutchison), South Dakota, has a W. Mc Onway listed as living with Klause and Rebecca (Walize) Oltmanns. He's listed as 12 years old, which makes a birth year of 1868. The 1870 US Census for Brookville, Ogle County, Illinois, has Rebecca Walize living with her parents, and it has a 2-year-old named Joe Burdine. Could this Burdine be the original name for Wesley Mc Onway before Rebecca married Klaus? I have found no Mc Onways in Ogle County. However, I found a William McInway on an Illinois tax assessment for 1864, but he resided in Blackberry, Illinois. I can not find any Burdine family in Ogle County, either.
