You should get two records, both for James.If the above link does not work, paste it into yur browser address bar and delete everything to the right of "birthdeath".Then hit return and you will get to the search page. scorll down to the bottom and enter the county and surname in the search death area.
On record states that James was buried in Independence, MO. My guess is in the Woodlawn Cemetery.
The Genealogy Dept. of the Mid Continent Library in Independence, MO has an index for this cemetery.
If you visit this link, and send an email request (See item 5) they can check the index and see if he is there, and see if they can get a death date for Sarah.If so, they should be able to check their "Examiner" newspaper index to see if a local obitary was published. I think they can also check the KC newspapers.
