Lizzie had gone to Central Congregational Church, which is now a culinary school and restaurant. The Bordens purchased their own pew. This was a common practice back then.
After the murders, Rev. Buck and Rev. Jubb were extremely supportive of Lizzie. They accompanied Lizzie to court daily and visited her during her incarceration.
After the trial, both pastors sorta dropped Lizzie. When Lizzie went to her church after her acquittal, she was snubbed so she quit going.
She was a religious woman throughout her life, which still makes me wonder just how guilty she was.
She was buried at a private service. The priest from the Episcopal church in FR - the Church of the Ascension - conducted the burial service. Since she had her burial instructions written down and her will in good order, she probably ended up being Episcopalian in her later life.
I am Episcopalian, and when I was in FR recently I went to their 10 AM service. (It was the only way I could get a look at the inside! They always locked the doors right after service.

) I doubt that Lizzie ever set foot in the church, but that doesn't mean the minister didn't go to her home to visit.
