Portis/Porter M. Coolbaugh

What I already knew:
My maternal grandmother was Nettie Emily Coolbaugh Cornell.  She was believed to have been born in Athens, Bradford County, PA in September 1882/1883.

Her parents were Portis/Porter M. Coolbaugh (b. 14 Nov 1844 Monroeton, Bradford, PA    d. 16 Oct. 1911  Oxford, NY).  (Porter’s first wife was Emily H. Arnout)

and Harriet Bowning Coolbaugh (b. about 1850 and died 1930)

I thought Portis was in the Civil War.  I was able to find on line a copy of his Application to the New York State Woman’s Relief Corps Home. Portis, at 66 years of age, filed his application in Genoa, Cayuga County, NY on 4 April 1910.  From that single document I was able to gather a lot of information. 
Portis  was a Private in Company C, 107th Pennsylvania Volunteers.  He enlisted on 1 Mar 1862 and was discharged at the end of his term 2 Mar 1865 at Hatcher’s Run, VA.   

From his application he stated he married Harriet on 22 June 1875 and they had 4 children: Max Morris 33 yo, Manda (Amanda) B. 30 yo, Netta E. 27 years, Charles D. 24 yo.  He stated he was born 14 Dec. 1844 in Town of Monroeton, Bradford County, PA.

He stated that while in the line of duty at Fetchers Chapel, near Falmouth, VA he was disabled after “contracted Pneumonia which left me with affected lungs and in the Summer of 1864 I had the second severe attack of Chronic Diarrhea which brought on Piles and disease of the Rectum which have troubled me ever since”.  “Since leaving the service he on July 1908 contracted by a fall was ruptured from which he is now suffering, and by reason of which he is unable to support himself by his own efforts and labor, that he therefore applies for admission to the New York State Woman’s Relief Corps Home.” (I was able to find information on the internet for the Battle of Fredricksburg, VA in December 1862.  Falmouth is across the river from Fredricksburg.)

The application states he did not own real estate or have a mortgage.  He had no yearly income.  He would start receiving a $14.00 per month pension, Certificate # 368477 payable at the Buffalo Agency commencing on the 12thg day of January 1910.
It looks like Portis and Harriet were both moving in to the Relief Corps Home.

The application also lists by great grandmother Mrs. Netta E. Cornell as a Patternmaker who lived at Atwater, NY R.D. 25

I also know by the application that my great great grandfather was able to sign his own name.

What I want to know:
