Looking for cause of death for Henley & Zepha HOLLINGSWORTH and Addison WILSON all of which died in 1927.

Single stone in Ebenezer Cemetery in Goshen OH list:
Henley HOLLINGSWORTH 1843-1927
Zepha HOLLINGSWORTH 1849-1927
(son)George HOLLINGSWORTH 1879-1947
Lloyd CAIN 1883-1951
Elizabeth CAIN 1888-1976
(back side below)
Addison WILSON 1861-1927
Alice HOLLINGSWORTH-CAIN 1871-1956

Could just be a freak thing, but I found it interesting that 3 mentioned above all died in 1927.
Illness, accident, etc.????

Thanks,
Kimberly
