Family tradition says the Hollenbeck's owned vast amounts of land in Marathon and Willet, New York, at one time. From the Cortland County Land Records, the following transactions are recorded, showing Jasper and his wife Mary Hollenbeck as the grantees (buyers), between 1910 and 1939. This is in addition to the lands they already owned prior to 1910.
The land Jasper purchased in 1917 and 1921 was located in Lots 76 and 77, shown on this old map of Willet, shown here in red:
Jasper's daughter, Rose (Hollenbeck) Leonard, owned hundreds of acres of land in the bottom left portion of Lot 76. What was once her driveway is now Leonard Road. You can see it on Google Maps here:
This modern map shows the location of Rose's property near the intersection of Routes 221 and 167.
