>William died in 1872 and Jane was apparently remarried by 1880, but I cannot locate a marriage certificate in Grant County, WI for her. There are too many places she could have gone to check without more details. Any ideas? From what you say here, I assume you've found Jane ELLIS T????? Farrey with a third husband in 1880. In that census, what is Jane's name, age and birthplace, and what birthplaces are listed for her parents? In Washington and Elizabeth ELLIS's household in the 1850 census, 13-year-old Yerelda J. is enumerated; the initial J might be for Jane. (Note, however, that there is a marriage record for Zerelda Jane ELLIS, to LLOYD L. CARTER on 24 Apr 1859 in Grant Co.) Also, consider this: Agnes appears to be Washington ELLIS's third (or later) wife, as he is listed with Elizabeth in 1850, with Nancy in 1860, and with Agnes in 1870. It may be that Jane is Agnes's daughter by a previous marriage. Note, too, that in 1850 and 1860 Washington has "extra" children with other surnames in his household; if no other explanation emerges, consider the possibility that Jane was fostered or adopted into the ELLIS household and considered Washington and Agnes her parents for the purpose of listing parents on a marriage record.
