I'm not related. Connor is about the most common Irish name which makes it harder to trace.
I suggest getting her death certificate from the PA Dept of Health. It should list her parents including her mother's maiden name. I also suggest getting her obituary. Check with the Western Pennsylvania Genealogical Society to see if they can help you. Her obit should also list surviving siblings.
You might also call the cemetery to see what they have on her in their records, be sure to ask who else is buried in the same plot and what parish she belonged to. Check with the church (parish) she was a member of. If you're not sure check the obit and with the Archdiocese of Pittsburgh.
