Släktträd means "family tree" in Swedish. The word comes from Släkt, meaning "the family" (earlier, from the Low German "Slecht", "descent" or "family"), and from Träd, meaning "tree".
Our most recent immigrant ancestor, Charlotta Olofsson, was Swedish, so her native language was used in naming this site. A reader of her biography will note that she conducted her three day courtship with her husband-to-be via a translator. And as a married woman, she dealt with Indian incursions and raids on her home in Franklin County, Idaho, USA, while knowing little English.
