I arrived in Dublin around 11am GMT this morning. I visited Trinity College today, there the Reverend John Walker had been a fellow. Walker had been a member and minister of the established Church of Ireland, but then converted to Sandemanianism. Upon his conversion, he was expelled by Trinity College. Walker founded several Sandemanian congregations in Ireland, which often went by the name of Walkerites or Separatists.
I’ve been attempting to locate Walkerite meeting houses in the Dublin area, but unfortunately they all appear to have been torn down.
