Marjorie, I have COOLBAUGH's back to 1720 NJ including Lillie, Zura, Isaac, Aaron, Peter, William Jr., and William Sr. This information is mostly from the book, The Coolbaugh Family in America, Hoagland, Edward Coolbaugh, 1938. I found it in the NEGHS Circulating Library. I'll be glad to share what I have with you. Whitney Laning [email protected]
