Hi Helga, There is not a Williams-Collins Cemetery in Guilford, or any other town in Windham County, Vermont. There is a Maplehurst- Elmhurst Cemetery. It is on East side of VT U.S. 5 several miles south of Guilford. It was formerly two seperate cemeteries. Elmurst was east of Maplehurst and last used in 1904.The Maplehurst side is still used. 1st burial was 1809. THANKS to D.F. for this lookup. Happy searching, Jan
