When using the Relationship calculator and Kinship report to determine my relationship to my grandfather’s brother, FTM 2014 lists my grandfather’s brother as my ‘Great Uncle’. It should be ‘Grand Uncle’.
When I check the relationship in reverse to determine my grandfather’s brother’s relationship to me, FTM 2014 correctly identifies me as his ‘Grand Niece’.
I understand that many people actually use Great Aunt and Great Uncle, but genealogically speaking, that is incorrect.
