Thanks Tom, for getting back to me. My Matchetts may have moved to Lisburn, as Deborah's marriage certificate gives that as the place she was from. Or only she, and not her parents, may have lived there. She was widowed when she married my ancestor, and the name on the certificate is Dorothy Robinson, However, it's once again Deborah on her son's death certificate and everywhere else. I can only think that the registrar at Lisburn Cathedral made a mistake when he wrote Dorothy. Joan.
