Good day, I am a descendent of Peter D'arcy as well. My great-grandfather was a brother of Joseph Elias D'arcy. I was in Ireland this past summer and hired a local headstone company to repair Peter's headstone that was in quite a state of disrepair. I'm still waiting on pictures to see the finished work. I also visited the ancestral family home. I would be happy to share any info with you and would be thrilled to see your family heirlooms. Hope you get this.
