My grandmother and grandfather are both deceased. My Grandmother's maiden name was DeRyder, not sure if that helps. My grandfather worked in the Moonachie fire dept., was also a mailman. My grandma was active in the community and with the senior citizens. I know several of the Van Sader's family lived on Frederick St in Moonachie very close to my grandparents. The twins were both male and would maybe be in their late 60's, early 70's. One of them subbed either in the Moonachie grammar school or Wood-Ridge HS. My dad had told me he was my second cousin. I think that's from my grandmother's DeRyder side. I think one of my grandmother's sister was married to a DeRyder and had the twins. I'm still trying to research it.
