I need your help finding “missing years’ data” of Randolph Sanford Rediker (b. 14 May 1868 in Ft. Fairfield, ME, died 01 April 1909 in Minneapolis, Hennepin County, MN) who is NOT accounted for in U.S. Census data for 1870 and 1880 for Maine or Minnesota. Here’s the problem: Randolph’s 1909 death certificate in MN lists his father as James Rediker, who we know was from Ft. Fairfield, ME, and lists his mother as Sarah J. Day, also from Ft. Fairfield. While his parents are not mentioned by name in the 1895 MN state census or the 1900 US Census, Randolph Rediker does appear in those two census listings as having parents born in Maine. So, sometime before 1895, he migrated from Maine to Minnesota. There is no undamaged 1890 US Census record covering his likely residences, and when you look at the 1880 and 1870 Censuses for Maine, when Randolph would’ve been about 11 ½ and 1 ½ years old, respectively (thus presumably living at home with his parents), you find James Rediker and Sarah J. Day Rediker, as husband and wife, living with several children but NOT with a son named Randolph Rediker or Randolph S. Rediker. (The James Rediker family is found in Brewer, ME in 1870 and in Ft. Fairfield, ME in 1880.) Can anyone help with this mystery?
