I have been researching my family genealogy as a hobby. Yesterday, a thought occurred to me: How would one record a transitioned relative? On paper, the situation could be explained on the person's family record sheet, but what about genealogy software? Some packages do "sanity checking" on entries so if you had a relative who was assigned male at birth, married a woman, fathered children, then got divorced, transitioned, and married a man who already had children of his own, the software would prevent you from assigning the second spouse.
It's largely a hypothetical question for me since I have no children and don't expect to have any, nor do I have any transsexual relatives... to my knowledge. I just got to thinking about it and realized most genealogy software makes assumptions that are not entirely compatible with LGBTIQ individuals.
For my own record, I think it will suffice to list myself according to my birth certificate and other documents, then create a Name Change event supported by the appropriate civil filing and note the change of gender identity in the same note.
