WITH THE FLOWERS AND TREES IN CALIFORNIA, by Charles Francis Saunders, 1914

"Vignes was a popular citizen in his time and lived in a house near the Los Angeles River with a fine old sycamore tree before it, of which he bragged as much as he did of his grape vines. The Spanish-American word for sycamore is aliso, and so he was nicknamed Don Luis del Aliso. The tree is long since swallowed up in the growth of the city..."

SOUTHERN VINEYARDS: The Economic Significance of the Wine Industry in the Development of Los Angeles, 1831-1870, by Cleve E. Kindall

"These were the economic conditions that Jean Vignes faced during his early days in Los Angeles. His experience and background turned him away from any connection with the city’s only major business, cattle, and led him towards the vine. He was able to recognize the shortcomings of the local vineyards, and, at the same time, realize the possibilities that the area represented. The soil and climate, he knew, could support an industry and produce wines comparable to Europe’s best. He is quoted as declaring that the area was 'just the place to grow them [oranges and grape vines] to perfection.'"

LOS ANGELES WHEN IT WAS “THE CITY OF VINES,” By Mrs. A. S. C. Forbes

"In 1829 or 1830, Jean Luis Vignes, a native of Bordeaux, France, came to Los Angeles to make his home. He secured 104 acres of land facing the present Aliso Street and extending to the river, and that he planted a vineyard. He named his place 'El Aliso,' from the stately old alder tree that graced the lot and shaded his wine cellars. This tree has been called a sycamore, but as the Spanish word for alder is aliso, and the Spanish word for sycamore is sicomoro, it would seem that the tree was an alder."
