Thank you all ever so much
I have contacted council & they have Carnmoney records & the don't have her or her father on records, so they gave me a contact for the Church of Ireland at Carnmoney, phoned them & they are going to look up records to hopefully
confirm her fathers burial ie James Duffield in Sept 1925 & see if Margaret was also buried with her parents.
I checked the Belfast cemetery records online and no joy, so if her funeral was St Columba's Knock which seems likely I will contact them after hearing from carnmoney C of I.
Thank you very much, hoping to find this grave
yours
