During most of his lifetime Bing celebrated May 2, 1904 as his birthdate. After Bing's death in 1977 a Tacoma priest disclosed Roman Catholic Church baptismal records that revealed Bing's actual birthdate. Contemporary newspaper reports of Bing's birth also confirm the date as May 3, 1903:
The Tacoma Daily News Wednesday, May 6, 1903:Apparently the family began celebrating May 2nd as Bing's birthday in deference to his sister, Mary Rose, who was also born on May 3 in 1906.
"Mr. and Mrs. H. L. Crosby are receiving congratulations on the arrival of a son at their household May 3."Tacoma Daily Ledger, Thursday May 7, 1903:
"A little son arrived May 3 in the home of Mr. and Mrs. H. L. Crosby".

Everett served for many years as Bing's manager.
Seeking work, Bing's family moved from Tacoma to Spokane, Washington, in 1906 where in the third grade Bing developed a friendship with an older neighbor boy, Valentine Hobart. The two boys shared an interest in a newspaper comic strip called The Bingville Bugle, and Bing would plead with Valentine to read him the strip. "Bing! Bing! Bing!" Valentine began calling Harry "Bingo from Bingville." Eventually the appellation was shortened to "Bing" and was adopted by Bing's other friends and teachers.
