I did not find a death reference for a James Lewis. However, there is one for a John Lewis who died 1885. There is no obituary but he does a have a probate record; Probate D, Page 328.
The following reference from the obituary books may be in reference to Catherine Lewis:
LEWIS (Probate
Court) Katy C. Lewis, as guardian of Ethel Q. Lewis, a minor, made her second annual settlement.
Benton County Democrat 7-23-1891
I would also check on these following probate records:
Box 22 - Lewis, John - 1888 Estate - Adm. B. Newkirk
Box 124 - Kate C. Lewis - 1935 Will - Adm. Ethel
