There are two organizations that are primary sources of historical information about the land and the early settlers of Hacienda Heights (Rancho La Puente). They are The Workman and Temple Family Homestead Museum and the La Puente Valley Historical Society. Both are local.
The Workman and Temple Family Homestead Museum has many events that are held throughout the year, particularly focused on the Workman and Temple family.
The La Puente Valley Historical Society is also a fine resource for information about John Rowland and La Puente City. They are directly involved with The Rowland Home and The Dibble Museum. The Rowland Home is currently being restored
