Family

Frank Lloyd Wright was married three times and fathered seven children, four sons and three daughters. He also adopted Svetlana Milanoff, the daughter of his third wife, Olgivanna Lloyd Wright.
His wives were:

• Catherine "Kitty" (Tobin) Wright (1871–1959); social worker, socialite (married in June 1889; divorced November 1922)
• Maude "Miriam" (Noel) Wright (1869–1930), artist (married in November 1923; divorced August 1927)
• Olga Ivanovna "Olgivanna" (Lazovich Milanoff) Lloyd Wright (1897–1985), dancer and writer (married in August 1928)

One of Wright's sons, Frank Lloyd Wright, Jr., known as Lloyd Wright, was also a notable architect in Los Angeles. Lloyd Wright's son (and Wright's grandson), Eric Lloyd Wright, is currently an architect in Malibu, California where he has a practice of mostly residences, but also civic and commercial buildings.
Another son and architect, John Lloyd Wright, invented Lincoln Logs in 1918, and practiced extensively in the San Diego area. John's daughter, Elizabeth Wright Ingraham, was an architect in Colorado Springs, Colorado and died September 15, 2013 of congestive heart failure. She is the mother of Christine, an interior designer in Connecticut, and Catherine, an architecture professor at the Pratt Institute.
Wright designed a house for David Samuel Wright, his son by his first marriage to Catherine, and David's wife, Gladys.
The Oscar-winning actress Anne Baxter was Wright's granddaughter. Baxter was the daughter of Catherine Baxter, a child born of Wright's first marriage. Baxter's daughter, Melissa Galt, currently lives and works in Atlanta as an interior designer.
His step-daughter Svetlana (daughter of Olgivanna) and her son Daniel died in an automobile accident in 1946. Her widower, William Wesley Peters, was later briefly married to Svetlana Alliluyeva, the youngest child and only daughter of Joseph Stalin. They divorced after she could not adjust to the communal lifestyle of the Wright communities, which she compared to life in the Soviet Union under her father, and because of the constant interference of Wright's widow. Peters served as Chairman of the Frank Lloyd Wright Foundation from 1985 to 1991.
A great-grandson of Wright, S. Lloyd Natof, currently lives and works in Chicago as a master woodworker who specializes in the design and creation of custom wood furniture.

Archives

From Wright’s death in 1959 most of his collections were stored at the headquarters of the Frank Lloyd Wright Foundation — Taliesin, in Spring Green, Wisconsin, and Taliesin West. The collection includes more than 23,000 architectural drawings, about 40 large-scale, architectural models, some 44,000 photographs, 600 manuscripts and more than 300,000 pieces of office and personal correspondence. The archive’s architectural models include notable Wright projects like the unrealized St. Mark’s Tower and a version of the Guggenheim. Most of these models were not made for clients; they were constructed for MoMA’s retrospective of Wright in 1940
