Chris, Thank you very much for taking the time to provide this information. I hadn't gotten any farther, since my last post. Myself and a cousin traveled to NJ Stone house plaine a few years back to follow the Manderville line and I wasn't able to do any follow up on Mary Garrabarants (Gerrebrantse).
In your research have you ever come across the name Grielstine? Seems the spellings of these dutch names have undergone Americanization and I've never been able to find this referenced anywhere. Mary's son Peter married a girl named Maria Grielstine, which we are also investigating, but this name seems unique.
