Death records are one of the things that we want to find for each ancestor. However, there are times when that record doesn’t exist. (Don’t you hate it when an ancestor dies before that state started keeping death records?!)
If you can’t find a death record and his or her tombstone hasn’t been found or is illegible, take a look at his or her will. You can get at least an estimate of when he or she died.
John Douglass’s will is included in the Pennsylvania, Wills and Probate Records, 1683-1993 collection. In the opening paragraph, he states that he’s writing his will on the “thirtieth day of January in the year of our Lord one thousand eight hundred and six.”
