In 1850 she is listed as Elizabeth Dill (53, PA) head of household. Living with her are Aaron Dixon, a farmer (38) born in OH, and Elizabeth Dixon (13) b. OH. They are living next to Wm Hastings, husband of Sarah Cooper. She was listed as born in PA in 1860 census and on her death cert. The marriage record to Isaac lists her name as Elizabeth Dill.
In 1870 Isaac is listed as age 70, born in VA, a farmer with $4,000 of land and $250 property. Listed with him is his wife Elizabeth (72) and step granddaughter Elizabeth Dixon. Listed above them was Aaron & Maria Dixon (47) who appears to be Elizabeth's dau from a previous marriage.
In 1880 census Elizabeth is listed as head of household, with Elizabeth Dixon listed as her granddaughter. Below them is Aaron & Maria Dixon family again. Her death certificate says that she was widowed and died in Jackson Twp of old age at 86 yrs, 1 mo, 12 days. It also says that she was born in Penn. and that her father was George Deheart, which is consistent with the assumption that her first marriage was to a Mr. Dill and they had a daughter Maria (b. PA) as listed next to her in the 1870 and 1880 census.
