Nettie Elizabeth Martin baptized 20 Dec 1868 Trinity Cathedral Episcopal, Omaha

Is further info available on this record from FamilySearch.org? I'm researching Nettie Elizabeth Martin b.1 Nov 1868 probably in Nebraska. Her mother may be Amanda Armstrong; father is reported to be Lieutenant Martin, US Army posted to Nebraska following Civil War. Nettie and sister were sent to live with uncle Christopher C Armstrong:
1880 US census, Globe School House, Greenup Co KY:
Chris. Armstrong 34 MO VA VA -- Minister of ME Church South
Frances 35 MO WVWV
Nettie Martin 11 MO WV MO -- Niece (Married TJ Kindel 1892 Albany TX.)
DOES ANYONE HAVE MORE INFO ON THIS MARTIN FAMILY? Thanks for your help.
