When Mary Catmull Hemingway and Martha Catmull Strack were born on the same day - Dec. 7 - no one was surprised.
They are twins.But when their dear mom gave birth to two boys - one on Dec. 7, 1921; the other on Dec. 7, 1931 - census bureau officials raised their eyebrows.
The chances of four siblings sharing the same birthday is indeed rare.
"What else could it be but a coincidence? You didn't plan anything like that 50 or 60 years ago," said Richard Catmull, a fifth family member who will be attending birthday festivities Wednesday.
Catmull, an employee of the Newspaper Agency Corp. and LDS Church Distribution Center, said the family has stayed close, even though their lives have gone different directions.
Mary and her late husband, Robert W. Hemingway, lived in Salt Lake City all of their 48 years of marriage. Martha, who now lives in Vallejo, Calif., once owned a cattle ranch in Sidney, Mont., with her husband James.
Earl is a retired Taylorsville High school principal, and Daniel is a retired letter carrier for the U.S. Postal Service.
Fourteen children were born into the Catmull family. Five died in the 1920-30's; three more passed away in 1984, '85, and '86 respectively.
