In the 1880 Census - James W Wood listed as married, father Elijah Wood listed as widowed and brothers are either single or widowed, Helen as listed as 'wife'. I think she is the spouse of James, not Elijah as noted.
Also the name spellings are off - probably transcription errors - James appears to be Ursley in an earlier census.
Might be a place to start. Good Luck.
