Maggie Jamison md Silas Daniel Smith - her death cert is on the Missouri archives website - Holt County died 11/19/1953 She also was b. Falls City, Richardson, NE - father Thomas Jamison, mother Rebecca Depaine.
Thomas Jamison is referred to in various places as Thomas Henry Jamison/Jimmerson/Jemison/Jimason.I first locate him in the 1880 Census of Lewis, Holt, MO as Thomas Jimason, the adopted son of Bennet Hood b ~ 1838 MO and wife Ellen b. ~ 1842 MO.
Thomas' wife Rebecca may be DePaine/Depayne/DeJane/Dejayne or anything similar.She remarries a Bradberry and is with youngest son Thom J. Jamison in the 1930 Falls City, Richardson Co. NE census.
This should give you some directions to go.
