IMO, I believe I have found another possible child of Rasmussen’s, born 9 Oct 1982 in Michigan. I have no reason to believe they are deceased. Guardianship was petitioned, in 1986, by two people with same last name. Notice of Hearing was published for Terry Rasmussen. I am assuming that since the hearing took place in probate court and guardianship was petitioned for female and male, that mother may have been “unavailable”. I suspect that the mother may have been the sister as her obituary, in 1896, mentioned a daughter of the same name and aligns with the petition year. JMO.
