I live in Tremont, Schuylkill Co., PA. Several years ago my husband and I transcribed all 4 cemeteries here in town. I checked the Catholic cemetery and there are a few Doran's buried there, however, I do not see any for Matthew and/or Hannah Doran. But that is not to say they are not buried there, as many stones are either broken and buried in the ground and or so worn away that we could not get a reading.
I can offer to check the death records in 1884 at the Schuylkill Co. Courthouse my next trip over.
