After the Widow Died

I'm working on a case where the husband's probate in the 1880s doesn't tell me very much. The widow survived. What I need to do is:

• search for a probate/will for the wife
• see if there are settlement deeds for any real estate after her death
• check for court action of non-probate courts in case there was an estate squabble after her death.

The problem may be that there just wasn't anything left to settle after her death.
