I found Joshus Davis married to Flora

1870 Wildwood, Craven Co NC

Davis Joshua 24 M B Farm Laborer

Flora 26 F B Keeping House

Henrietta 14 F B Farm Laborer

Samuel 1 M B At Home

I can not find Henrietta or Samuel in 1880.

1880 James City, Craven Co NC

Davis Joshua B M 43 Fisherman

Flora B F 40 Wife Seamtress

Riley B M 4 Son

1900 Township 7, Craven Co NC

Listed under Jasbo David, but record says Joshaway Davis

Davis Joshaway Head B M Born Feb 1868 Age 52

Blunt Riley R Adopt Son Born Apr 1882 Age 16

Any information about this family is needed. I can't figure out how

Riley was a son in 1880 and an adopted or step son in 1900 with a different surname.

I can't find father or son after 1900. I assume the mother died before 1900. I am researching Rileys of any surname and stumbled upon this family.

Thanks
