Family abandonment

Local gossips noticed Wright's flirtations, and he developed a reputation in Oak Park as a man-about-town. His family had grown to six children, but Wright was not paternal and the brood required most of Catherine's attention. In 1903, Wright designed a house for Edwin Cheney, a neighbor in Oak Park, and immediately took a liking to Cheney's wife, Mamah Borthwick Cheney. Mamah Cheney was a modern woman with interests outside the home. She was an early feminist and Wright viewed her as his intellectual equal. The two fell in love, and they became the talk of the town, as they often could be seen taking rides in Wright's automobile through Oak Park. Wright's wife, Kitty, sure that this attachment would fade as the others had, refused to grant him a divorce. Neither would Edwin Cheney grant one to Mamah.^{[citation needed]}
In 1909, even before the Robie House was completed, Wright and Mamah Cheney went together to Europe, leaving their own spouses and children behind. By this point Wright "rejected" the Prairie Style single-family house model of the upper-middle class, and hoped to work on more democratic architecture. He was not getting larger commissions for commercial or public buildings, which frustrated him.
What drew Wright to Europe was the chance to publish a portfolio of his work with Berlin publisher Ernst Wasmuth. The resulting two volumes, titled Studies and Executed Buildings of Frank Lloyd Wright, were published in 1911 in two editions, creating the first major exposure of Wright's work in Europe. The work contained more than 100 lithographs of Wright's designs and was commonly known as the Wasmuth Portfolio.
Wright remained in Europe for almost a year and set up home first in Florence, Italy — where he lived with his eldest son Lloyd — and later in Fiesole, Italy where he lived with Mamah. During this time, Edwin Cheney granted Mamah a divorce, though Kitty still refused to grant one to her husband. After Wright's return to the United States in October 1910, Wright persuaded his mother to buy land for him in Spring Green, Wisconsin. The land, bought on April 10, 1911, was adjacent to land held by his mother's family, the Lloyd-Joneses. Wright began to build himself a new home, which he called Taliesin, by May 1911. The recurring theme of Taliesin also came from his mother's side: Taliesin in Welsh mythology was a poet, magician, and priest. The family motto was Y Gwir yn Erbyn y Byd which means "The Truth Against the World"; it was created by Iolo Morgannwg who also had a son called Taliesin, and the motto is still used today as the cry of the druids and chief bard of the Eisteddfod in Wales.
