In 1940 and 1941 Mrs. Sterling B. Jordan and Mrs. Frank W. Seth walked the 18 cemeteries in Poundridge, New York compiling the names and dates for all gravestones. Added to some of those gravestone listings were familial relationships if known. In addition, they referenced an even earlier listing of a few of the cemeteries by William Eardley taken in 1901.
Compiled military service records for 1,235 Rough Riders, including Teddy Roosevelt have been digitized. The records include individual jackets which give the name, organization, and rank of each soldier. They contain cards on which information from original records relating to the military service of the individual has been copied. Included in the main jacket are carded medical records, other documents which give personal information, and the description of the record from which the information was obtained.
