William Johnston, death June 27, 1877 Pennsylvania

[Peggy13]

William Johnston was reportedly born May 19, 1814 in Co. Fermanagh, Ireland and reportedly died June 27, 1877 in Pennsylvania. Looking for his death certificate and an obituary to confirm his parents names and siblings. His parents may or may not be George Johnston and Susan Armstrong. Thanks for any help. Peggy
I do not know where in Pennsylvania that William died.

Pennsylvania didn't require statewide vital registration until 1906, so there might not be a death certificate.
