Same Name, Same Family?

While researching Eugene Cook in New York and New Jersey in the 1800s and 1900s, I come across his doppelganger.  Eugene Everett Cook.  They were born about twenty years apart and seem to have no blood relation.  On my most recent trip to Trenton, I was not even looking for this other Eugene Cook and poof- I came across his death certificate.

This Eugene Cook died in Orange, Essex County, New Jersey in 1943.
He was born in Brooklyn in 1878 to Lyman Cook and Sarah See.

This Eugene Cook died in Florida in 1979.
He was born in Newark, New Jersey in 1898 to Charles Cook and Minnie Bishop.
