Trying to find birth information on John Nippameck Kupp, born about 1853 in New Jersey.
Father was Mathew Kupp who died about the time John was born. Mothers name was Elizabeth Broderick from Ireland.

After the death of Mathew Kupp, Elizabeth moved to Mendocino California. Her son John followed about 2 - 3 years later.

John had three children with only one suverving - Mary.
I'm at a dead end so any help or direction would help!thank you
