My first guess would for the parents of Willie and Eddie would be the C.L. and Adelia Orcott found in Stearns County in 1870.There's some conflict about place of birth for C.L. matching between the two reports, but I think that's minor.
I'm looking at the remainder of my Orcutt records and none of the other MN Orcutts readily qualify, and the disappearance of both C.L. and Adelia support the theory that they may have passed away between 1870 and 1880.
