Both Mountain View and Horizon View are enumerated in Lauretta Harris' book: VITAL RECORDS OF THE TOWN OF SCHODACK. I have a copy and could do a couple lookups for you. The book is known to have some errors, but like any compilation, it is a great start. I believe all the cemetery information from this book is also available on the Web at rootsweb's GENWEB page for Rensselaer County. Ned Schimminger, just outside Niagara Falls
