In 1906, Peck married British-born illustrator John Scott Williams (1877–1975)...Peck and Williams shared similar styles, leading the two to occasionally collaborate on illustrations together. These works were signed with the first initials of their last names, "P W". Some of Peck's works are also credited as Clara Elsene Williams and the press sometimes referred to her as "Mrs. John Scott Williams". (From Wikipedia Article about Clara Elsene Peck)
