Confirmation on James H. Tomb's Sons? --Part 1

I sure spent a lot of time looking to see if there was a family connection between James H. Tomb, James Harvey Tomb and William Victor Tomb.  I did find one source at Wikiversity that said William Victor Tomb's father was James Hamilton Tomb.  He also had a brother who became a naval officer.  Could that be James Harvey Tomb?

I kept looking and then came across a site detailing some of the holdings of the University of North Carolina.  In it was:

COLLECTION NUMBER: 00723
COLLECTION TITLE:  JAMES HAMILTON TOMB PAPERS, 1855-1936

It takes up .5 linear feet of space and contains approximately 350 items.

James Hamilton Tomb was the chief engineer in the Confederate and Brazilian  navies and an officer  of the Norfolk and Western Railroad.  The collection contains the papers of two generations of naval officers.

Two generations.  That would be a confirmation for William Victor Tomb, but what about James Harvey Tomb?  He would also be the second generation.
