I think I might have found something else that applies to your William. There is a border crossing from Canada to Malone, NY dated 5 Sep 1930. William Ashworth was 55 years old. Under place of birth, it says (Nat. Blair Co. PA, 3rd Aug 1911). His home address was 2 Merrill Place, Geneva, NY. Also crossing with him were Edna Ashworth, 39 years old, born Birmingham, Pa. 23 Jun 1891 and living at the same address. Traveling with Edna was Ethel age 2 years 11 months.
William, Edna, and Ethel also traveled from Liverpool to Quebec, arriving 4 Sep 1930. Their passport number was 208986 issued 24/4/1920 in Washington. Same Geneva address. Ethel was born 31 May 1927 in Geneva, NY.
I found the family in Geneva, Ontario Co., NY in the 1930 Census at 2 Merril Place.

Ashworth, Edna Z., wife, age 39, age at first marriage 31, born Pennsylvania, parents born Pennsylvania, no occupation
