Found marriage records indicating parents are Jerry Wright b. VA and Charity Miller, for both Jeremiah and his brother George. Jerry Wright and Mary Kent are both noted as 2nd marriages. Found other Jerry Wright marriages in IL - but not enough information to confirm that is the correct man. One marriage seems unlikely when looking at dob and marriage dates? (Not included here a J B Wright married Elizabeth Higgins in Crawford IL in 1867 and a JB Wright married Martha Pleasant in 1876 in Jackson, IL. Again, can't tell if there is any relationship to father or son. )
