In the rural Massachusetts town of Dunwich, Massachusetts on February 2, 1913 at 5 a.m. Lavinia Whateley gave birth to a son, Wilbur Whateley. The date of his birth is noted for the night before the hills rumbled and dogs barked incessantly. Dogs continued to show an instinctual hatred for him for the remainder of his life. Wilbur was immediately recognized for his hideousness, described as a "dark, goatish-looking infant".
He displayed unnaturally rapid physical and mental development: At seven months he could walk unassisted and eleven months could speak. At four and a half, he appeared fifteen and he began to grow facial hair. "Though he shared his mother's and grandfather's chinlessness, his firm and precociously shaped nose united with the expression of his large, dark, almost Latin eyes to give him an air of..well-nigh preternatural intelligence.
At a young age he takes to wearing very coversome clothes. He also has revolting odor, a defining characteristic of the Old Ones.'Wilbur's voice is distinctive for its "Strange, resonant fashion which hinted at sound-producing organs unlike the run of mankind's". This presumably allows him to speak the language of the Old Ones. At 15 years he had grown to 9 feet tall and showed no sign of stopping.
