Lassen Family Genealogy Forum
Peter Lassen was born in Denmark in 1800 and was killed in CA in 1859. Some say he was killed by indians, but that is questionnable.
He was considered a trailblazer under Fremont and also a naturalist. To the best of my knowledge there is no verifiable documentation that he married; however, that does not preclude that he fathered children. Unfortunately most of the readings were written well after his death, so you must read them with questionnable authenication.
