I found an entry on Find A Grave.com for John Hoff 1847-1920 Husband of Emma Dennia, son of Thomas B. Hoff and Johanna Truax, at the Old Truax Burying Ground in Keansburg.
also Emma Dennis Hoff
Age 55 years
Daughter of Kate Henry Dennis of Eatontown, New Jersey
Wife of John W. Hoff in the same cemetery, but no grave marker found.
My grandmother was a Dennis from Eatontown NJ, but I do not have a Kate Henry Denis in my records. Very common surname though.
Hope this helps you! Regards. \http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GSln=Ho...
