I’m guessing from the census references that you really want the 1860 Census. I checked the 1870 census for these people but they were not there – a 2nd clue.
1860 Census of Brown County, Illinois, Pea Ridge Twp
1601/1539 29 Aug 1860
Henry Hearn 32 m farmer Germany
Mrs. C. Hearn 31 f Germany
H. H. Hearn 9 m Germany
Felice Hearn 6 f Germany
Ester Hearn 36 f Germany [On re-reading the film, the given name really looks like Ester instead of Etka.]
Riand Hearn 11 m Germany [This given name is strange but clearly written.]
Fear Hearn 12 f Germany [Ditto on this given name.]
Angeline Hern 60 f Germany
Han Hern 39 m farmer Germany [Given name looks like Hare, I guessed Han – you get to choose.]
Albert Hern 21 m farmer Germany
I am interested in the Hearn names listed in the index for the 1870 census.
Etka Hearn P1602
Henry Hearn P1601
Angeline * Hearn P1604
Any help you may give is appreciated.
