...I saw your post about F. P. Still. 
I checked for anyone named "Still" in the 1880 Federal Census for Kansas - no luck for a match.  I checked for anyone named "Still" in the 1880 census with a birth year of 1857:  Fred Still, age 22, born in Iowa was listed as the step-son of John F. "Calendar", age 67, born in Pennsylvania, a farmer in Bradford Township, Chickasaw County, Iowa.  John's wife was Anne, age 50, born in Ohio.
Backtracking to 1870, Bradford Township, Iowa: John Callender (age 58, B. Penn.) and his wife Ann (age 40, B. Ohio) other Callender's (ages 19 - 9mos, B. Penn/Illinois/Iowa) and Fred "Hill"(age 13). (J. W."Calender", age 24, B. Penn., was working as a school teacher in Auburn Township, Fayette County, Iowa).
1860, Bradford Township: John F. Callender, age 48, B. Penn. - household included Hannah Callender, age 46, B. Penn. and John  (25), Albert (21), Jonathan (17), Montgomery (9), Louis (7) - all born in Penn., plus William, age 5, b. in Illinois. 
I cannot find the Still family in the 1860 census, but two trees posted on (by and ) have the following info:
Ann Langdon married Franklin P. Still in Boone, Illinois on July 1, 1853.  Their son, Fred P. Still was born in Chickasaw, Iowa on Dec. 3, 1857.  Franklin P. Still died about 1865 at Vicksburg, Mississippi (another record says he died of disease there on July 17, 1863 - ironically, my own great-great grandfather died there at about the same time, of disease).
John Franklin Callender married Hannah S. Harned in Luzerne County, Penn. on Jan. 24, 1833.  They had ten children - the fifth son was Jonathan W., born Nov. 2, 1845 in Huntington, Luzerne County, Penn.
A cemetery transcription record on the Chickasaw County, Iowa USGenWeb site says that Hannah died in 1865. ( John F. Callender, who died in 1894, is buried in the same cemetery.)
Anne Still married John Callender in Chickasaw County on April 1, 1866.  They had three children together.  Anne died in North Dakota on Nov. 24, 1905.
The 1880 Census lists Fred Still as a single male (not married or widowed).  Confusingly, The site lists him as married to a Dora Drake, born on May 31 1862 in Osage, Mitchell County, Iowa as of Nov. 15. 1863.  However, it also lists her as dying in Stockton in 1871.   Go figure.
So, F. P. Still was Jonathan's step-brother...
