Spent some time looking for John Oates/Oades in the 1870 census this week.
John Oades (Oates) born 8-15-1819-England-farmer
Wife: Cecelia-born 4-12-1816-England
Son: Richard-born 1841-1842-England
Son: William? -single-born in IL? 1855 or so
Daughter: Ablen (Ellen) IL-1858
Son: Edwin -9-23-1866
I got side-tracked by a John Oats married to a woman of the right name with a son Fergus in the household, wrong age, and then stumbled on the right family searching for people named John, born in England, in Cook County. If I hadn't known that they had lived in Northfield in 1880, I might have skipped over it.
