I know this is an old inquiry, but I think we may be able to help each other. My GGGrandfather was Colin Livingston and he lived on PEI, moving from Cape Breton with his wife Catherine. They had a daughter Katherine that lived in the USA and I believe it is the same person. I have found Catherine's death certificate and her father Colin is the only Colin Livingston I am aware of who was from Cape Breton in that time period. Please contact me so we can compare notes.
