I have run into a brick wall regarding further investigation of my 2nd great-grandfather, Jacob Tryon.I knowthat he married Amelia B. Davis (b: 5 Aug 1847 in Philadelphia, Pa) I believe that they were married approx 1872 or 1873 in the Philadelphia, Pa area as my great-grandfather, Charles P. Tryon, was born on 20 Sept. 1873. I know that Jacob Tryon and his wife Amelia lived in Philadelphia in 1880 with 2 of their children because of the 1880 U.S. Census. I know that Amelia Tryon is listed living on 9th St in Philadelphia as a widow w/2 of her children on the 1900 U.S. Census and the marriage is indicated to have lasted 27 yrs. Jacob Tryon was listed in the 1900 Philadelphia, Pa. City Directory as living at the same 9th St. address as was indicated for Amelia and children living there in June 1900. I know that Amelia and her children Charles P. and Lillie May are buried together at the West Laurel Hill Cemetery in Bala Cynwyd, Montgomery County, Pa but apparently Jacob is not buried there. I looked into the possibility that Jacob served in the Civil War because of his age and found a record of Jacob Treon who died on March 6, 1900 or March 6, 1910 in Pennsylvania. This would fit with the timeline of Amelia being a widow in June, 1900 but not with the 1910 death date. At any rate, this Jacob Treon/Jacob R. Trion was born in 1840 and buried at the Brock Cemetery, Ashland, Schulkill County, Pa and he was a Private with Bates' Pennsylvania Volunteers: the 152nd Regiment/Third Artillery, Pa. Since there were so many Jacob Tryon's in Pennsylvania during this period, I don't know where to go next. I have looked up each child born to Jacob and Amelia hoping for some clue about Jacob's ancestry, but was unable to find anything new. Any help and assistance would be greatly appreciated.
