McDonald Family

The McDonald family of California was a wealthy and influential family whose principal public legacy was established in Santa Rosa during the second half of the nineteenth century and the first half of the twentieth century. The family descended from Colonel Mark Lindsay McDonald, a Kentucky-born engineer and entrepreneur who came to California during the early 1850s as the captain of a wagon train. He initially worked on roads serving gold- and silver-mining districts, then expanded into property development, utilities, transportation, and agricultural businesses. McDonald became associated with the commercial and civic development of Santa Rosa. During the late 1860s he acquired and subdivided approximately 160 acres, creating what became known as McDonald's Addition. The development helped establish McDonald Avenue as one of the city's leading residential streets. Its attractiveness was supported by improvements connected with McDonald and his enterprises, including gas and water services, a streetcar line, tree planting, and nearby recreational and landscape projects. McDonald was also involved in the Santa Rosa Water Works Company, an early private utility, and helped bring a steam railroad to the city. He financed and built the reservoir later known as Lake Ralphine, named for his wife, Ralphine North McDonald. His other commercial interests included fruit-packing facilities, drying yards, orchards, and real estate. The family occupied an elite position in California society. McDonald held a seat on the San Francisco Stock Exchange and was connected socially and commercially with figures such as George Hearst, Leland Stanford, and Charles Crocker. Although the family's principal residence was in San Francisco, the family estate in Santa Rosa, originally called Mableton and later widely known as the McDonald Mansion, served as a summer home and became the central symbol of the family's local prominence. Colonel McDonald and Ralphine had seven children, although two daughters died in childhood. Their surviving children included Mark Lindsay McDonald Jr., Stewart, Mabel, Edith, and Florence. Mark Jr. eventually inherited Mableton and continued the family's business activities. He operated the Santa Rosa Water Works and the M. L. McDonald Jr. and Co. fruit-packing business, while also holding orchard land and other real estate. He married Isabelle Juilliard, whose family was also prominent in Santa Rosa and whose uncle Augustus D. Juilliard was associated with the later Juilliard School of Music. During the 1920s, Mark Jr. and Isabelle undertook substantial alterations to Mableton. The work included changes to the rear of the residence, additional bathrooms, and extensive landscape improvements. A tennis court was added to the grounds, on a site later used as a formal garden. Mark Jr. died in 1932, after which Isabelle spent most of her time in a Nob Hill apartment in San Francisco and used Mableton primarily as a summer residence. Their son, Juilliard McDonald, maintained family business interests but died childless in 1946. Their daughter Marcia ultimately became the last surviving McDonald heir. After Isabelle's death in 1960, Marcia inherited the family position connected with Mableton. She lived mainly in San Francisco and visited the property less frequently, allowing the mansion and grounds to deteriorate. When she died in 1971, the terms of Isabelle's will and trust directed that Mableton pass jointly to Stanford University and the University of California. The property subsequently became the subject of local debate over its future and possible development. It was eventually offered to the City of Santa Rosa, but an environmental impact review concluded that single-family ownership was necessary. Jack Leissring purchased the property in 1974. He later sold the house in 2005 while retaining the carriage house. The McDonald family is therefore best understood not as a continuing consumer brand or operating comp…

The family's California history began with Colonel Mark Lindsay McDonald, who was born in Kentucky and traveled west during the early 1850s as captain of a wagon train. With engineering experience, he built roads serving mining districts and used the resulting wealth to enter property development and financial circles. He later acquired a seat on the San Francisco Stock Exchange and became connected with leading California businessmen and developers. By the late 1860s, McDonald had shifted substantial attention to Santa Rosa. He purchased and subdivided roughly 160 acres, creating McDonald's Addition, a residential development that helped shape the city's expansion. McDonald Avenue became its principal residential thoroughfare. The development was supported by utility and transportation improvements, including gas and water services and a streetcar connection. McDonald also encouraged extensive planting and landscaping, working in a community that benefited from the horticultural influence of Luther Burbank. McDonald's interests extended beyond land. He was involved in Santa Rosa's first library, helped bring the first steam railroad to the city, and operated or supported the Santa Rosa Water Works Company. He financed and built a reservoir named Lake Ralphine after his wife, Ralphine North McDonald. His agricultural and commercial portfolio included orchards, fruit-packing facilities, and drying yards. These activities made the family important participants in the development of Santa Rosa's infrastructure and regional economy. The family's main home was in San Francisco, while Mableton in Santa Rosa functioned as a summer residence. The house and grounds expressed the family's wealth and social position. Mark and Ralphine McDonald had seven children, with several surviving into adulthood, including Mark Jr., Stewart, Mabel, Edith, and Florence. Their marriages connected the family to other prosperous San Francisco and California families. Mark Lindsay McDonald died in San Francisco in 1917, followed by Ralphine in 1918. Their son Mark Jr. and his wife, Isabelle Juilliard, eventually became the principal owners of Mableton. Mark Jr. continued the family's commercial pattern by operating the water works and a fruit-packing company and by maintaining orchard and real-estate holdings. In the 1920s, he and Isabelle remodeled Mableton, adding bathrooms, modifying parts of the house, and improving the landscape with features including a tennis court. Mark Jr. died in 1932. Isabelle thereafter used Mableton mainly as a summer property while maintaining a primary residence in San Francisco. Their son Juilliard continued family interests but died without children in 1946. Isabelle died in 1960, leaving Marcia as the last surviving heir associated with the estate. Marcia lived mainly in San Francisco and allowed Mableton to receive limited attention. Marcia's death in 1971 ended the direct line of heirs associated with the mansion. Under the terms of Isabelle's will and trust, the property was intended to pass jointly to Stanford University and the University of California. Its future became controversial in Santa Rosa, where possible development raised preservation concerns. After an environmental review favored single-family ownership, Jack Leissring purchased the property in 1974. The house was sold in 2005, while the purchaser retained the carriage house. The family's legacy now rests principally in the historical record of Santa Rosa's development and the preservation history of Mableton, which is also known as the McDonald Mansion.
