The Hollenbeck DeMolay Mother's Club and all DeMolay Mother's Club Circles have their roots in the Masonic Temple Order. Mothers of sons who become DeMolay members are "automatically" members of any Masonic Mother's chapter. The Hollenbeck DeMolay Mother's Club by-laws of 1928 assert that, "the object of this club shall be to raise funds to help the DeMolay boys purchase paraphernalia and equipment used in their order." Each temple had a Mother's club, and the Mother's clubs were organized into larger "circles."

Los Angeles and its environs had approximately thirty-seven Mother's clubs within its Grand Council of Mothers Circles. Officers were elected every four months and could serve once in any one position. The Hollenbeck area of Los Angeles is near Evergreen and Chicago avenues in the Boyle Heights district just east of downtown. Many of the earliest members had addresses on these very streets. Today, the Mother's Clubs have become Parents Clubs and combine the dual energies of parents to "cooperate with and assist the Advisory Council of the Chapter in promoting the growth of the Chapter and its members, and to serve the Chapter and strengthen the interest of each member in DeMolay." In addition, the responsibilities have grown as members now take on transportation roles for members who do not have cars or are unable to drive to meetings. While the Hollenbeck DeMolay Mother's Club disbanded around 1977, DeMolay Parent's Clubs still flourish in Southern California and other parts of the United States.

Largely philanthropic in nature, the Hollenbeck DeMolay Mother's Club raised funds in a variety of ways, most notably through donations, endowments, baked cake/gift raffles, and 'bunko' parties throughout the year. Within the Masonic Order, donations were made for families in need, as well as for happier occasions such as weddings and births. The Mothers also kept in good order the robes used for installation of Masonic officers and the Master Councilor. They were in charge of securing and maintaining the building's fire insurance on which this regalia is listed as worth $297.00. The Mothers provided the legwork for many different functions and refreshments for all of the ceremonies within the Masonic Temple. Furthermore, the Mothers donated yearly to the Masonic Homes Endowment Fund which provided for the residence and education of boys. The Hollenbeck DeMolay Mother's Club provided funds for needy children to attend camp and on one rare occasion, donated blood for the care of a hospitalized member. The Mothers met at the home of one of its members, who provided refreshments, and where they conducted business and socialized. Today, no De Molay Mother's Club is registered within the Los Angeles area, but there are many chapters in other areas such as Orange County.
