Both Brothers Alfred Waud and William Waud were born in London England and prior to emigration to the U.S. lived with their parents in the London  Districts of Marylebone and Paddington. The family  consisted of the following:- Parents.= Alfred Waud b. Feb.21st 1796 in London, occupation, Carver and Gilder his wife was Mary (Nee) Fitzjohn b. November 19th 1806 in Swansea South Wales, occupation  School Misstress and owner of School for young Ladies in London. She educated all her children. Alfred and Mary were married on October 4th 1827 in Paddington, London, their children are as follows, Alfred (A.R.W.) b.Oct.2nd 1828, William b.1832, Mary Priscilla b.1833, Julia b.1834 and Josephine b.October 20th1840.
Julia and Josephine remained spinsters but Mary Priscilla married in 1862 to Augustus Cory Scoles, a Solicitor of Londonand the son of a famous London Architect. Joseph John Scoles. Alfred Waud Snr died Feb.5th 1858 aged 62yrs and Mary died June 6th 1891 aged 84yrs, same year as the death of her son A.R.W. .In 1841 the Census showed the Family living at 51 Cirencester Place Marylebone now known as Great Titchfield Street, Nr Regents Park, London. The information you have from Frederick E. Ray,s book, which I have read, is correct up to  a point, however the Family name did not come from Vaud in Switzerland, but it stems from the  old English Anglian for a Forest, and its original spelling was Wald and means "man of the  forest* It evolved as a surname after the Norman Conquest, because before this time the Anglo-Saxons had no surnames as we know them today. The name appeared in Yorkshire as Wald,Walde,Wold,Wolde, Wand, developing into  its modern form as Waud,Waude, and Waudby. I have traced it back to the  13th and 14th Century, long before the Canton of Vaud came into existance. Wald is Germanic in origin and you can find place names in Germany and Switzerland with this spelling because it means Forest. Vaud translates into river crossing and the V is pronounced F. like our English Ford.
The other misunderstanding is that Alfred R. Waud,s wife was called Mary Gertrude JEWELL and not  Jewett as in the book.
Census records show she was born in New York but it is not known if this was New York City or New York State. It is believed that her ancestors were French.
I hope this information will help you to understand the Artistic background the brothers came from as their Grandfather, William Waud b1765 was also a Carver and Gilder and later became a Professor of Music and his other children became well known musicians of their day. in London.
I have tried to find the marriage records of A.R.W. and his wife Gertrude Mary Jewell in the USA but without success, I think they were married in New York City or maybe Boston, I also failed to find any record  of the passenger lists for 1850 when the brothers came into New York from Liverpool but I think the lists for 1850 were destroyed. By the way, the middle name Rudolph did not appear until ARW was in the US, I think he adopted it to enhance his artistic image, and he continued its use by giving it to his son. (Credits: Ancestor- John W. Waud of Barry, South Wales  U.K. conducted Genealogical study).
In his youth is was decorator apprentice, but when he became of age he began to study art at the School of design at Somerset House, London. After a brief while as a scene painter for the theaters, he filled his dream and came to America. He landed in New York in 1850 armed with a letter of recommendation from John Brougham a popular Irish actor and playwright. Working in several occupations in an artistic nature he went to Boston and learned to draw on woodblocks for engravers.

He produced illustrations for various publications in Boston and New York during the 1850s, including work for Barnum and Beach's Illustrated Weekly. He became a skilled marine painter to which he devoted much serious study and landed a positions an illustrator for the New York Illustrated News in 1860.
With the outbreak of the war in 1861, three leading illustrated weeklies, Harper's Weekly, Frank Leslie's Illustrated Newspaper and the New York Illustrated News dispatched out their " Special Artists" and "Special Correspondents" to cover the war fronts. Alfred Waud, Esq., one of the most talented artists will proceed to Washington and will accompany the army through the campaign.
Soon after Waud arrived in Washington he sketched Colonel Elmer E. Ellsworth"s New York Zouaves, after the regiment help put out a fire at the Willard's Hotel on the night of May 9.

A photograph of Waud in July 1861 at Matthew Brady's Washington Studio just before or after Bull Run. Suited up for the field, with drawing gear, haversack, bowie knife, revolver, flask and bed roll. Waud was very much a fellow who sleep with the soldiers to get a feel for their experience.
