Today I saw 2 tombstones in the Union Dale Cemetery, Brighton Road, Pittsburgh PA 15212, Allegheny County, Division One, Section K:
L.O. TAFEL, Apr 13, 1812 - Feb 4, 1886, Father, "A native of Stuttgart Germany"
Edward F. TAFEL, 1847 - 1922, Father
I have no other info as it is not my line.
I hope this is helpful to someone.
