When transferring information from Geni to WikiTree what information is transferred from a Geni GEDCOM into WikiTree?
GEDCOMs from Geni include all the basic details that WikiTree needs in order to reconstruct your family tree.
Each individual person is exported with their given name, their surname, and if applicable, their married name. Unfortunately their given name is not broken down into a first name and middle name.
Birth, death, and marriage dates will be included.
Each parent, spouse, and child relationship is included. Siblings, grandparents, grandchildren, etc., are all inferred from these primary relationships, e.g. if two people share a parent they are siblings.
Geni will include links to photos, but not the photos themselves. GEDCOMs are text files so they can't include multimedia.
Sources are often missing from Geni GEDCOMs, presumably because the source is the person who created the profile on Geni.
