AN ITCH THAT NEEDS SCRATCHING

I'm wondering if any of my genealogy friends have ever had this happen to
them:

I was putting together a post about my 3x great grandfather Nathaniel Barker's
War of 1812 Pension file and had the pedigree view up on my RootsMagic5
database. I wanted to check on the death dates for Nathaniel and his wife
Huldah(Hastings)Barker because of something in the Pension File. Nathaniel
died on 12Mar 1884 in Bethel, Oxford, Maine; Huldah didn't survive him for
long, passing on 7Jun 1884 also in Bethel. Well, they were both elderly, 90
and 86 years old respectively, and perhaps Huldah was overwhelmed by her
grief.

But then I happened to glance over that the box for their youngest son, my
2x great grandfather Nathaniel S.(I believe the S stands for Swan for his paternal
grandmother Nancy Swan) Barker. He died a week after his father on 20Mar
1884 in Albany,Oxford, Maine. That got my attention. How could I have not
really noticed that before? Could it just have been coincidence or was there
more to it? Was there some accident involving the two Barker men, leaving
Huldah died of grief after? Or was there another outbreak of an some disease
in the area that claimed all three lives?  Since there had been seven members
of my West family that died in an outbreak of diphtheria in Mane in 1862.

I've got a copy of the death record for Nathaniel S. Barker but it doesn't give
a cause of death. I have not been able to find any for his parents.  Going to
Maine is not an option for me since I don't have the means to get there at
this time. I'm hoping to find an obituary or newspaper report eventually.

This is turning into an itch I need to scratch.
