Listed as “Keeping House” in 1870 census.

There is a Sara Jane Coll listed in the 1850 USA census for Elk, Clarion, PA, born around 1843, that may be here. If it is her, then Her parents are John & Mary Ann (b. abt 1818, Germany & 1825, Pennsylvania, respectively), and she had a little brother Jacob (b. abt 1849). Clarion County is just one county north of Armstrong, so this makes sense.

If this is her, then the 1860 census shows 3 more siblings: Parintha (b. 1850, female), Cynthia (b. 1856), and George (b. 1860). It also shows John being born in Hessiea, Germany around 1815. In this census the last name is spelled Call. There is also a Henry Call living ther, born around 1830 (younger brother of John, perhaps?).
