Clear Evidence Mary Cosby Is Unrelated To Bill Cosby

Bill's brother's full name was Robert Leroy Cosby, and Mary's husband's full name was Robert C. Cosby.

Salt Lake City, Utah: If Mary Cosby returns in The Real Housewives of Salt Lake City, then one thing is certain, the show will be a super hit.

More than that, sooner or later, controversy will boil, given her history of causing trouble.

Why we say this?

Well, yet another time, the Real Housewives star has gotten herself involved in controversy. During the shoot of the reality show, she called the forbidden R word to the 12-year-old son of Lisa Barlow.

This incident occurred when Lisa and Mary got into a heated argument in March 2024.

Is this the first time she has said something inappropriate like this?

Well, of course not; back in season 2, she said Jen Shah was a Mexican Thug even though Shah had Hawaiian and Tongan origins.

Due to the controversy, she has been in the news for the past few days.

Key Takeaways

Bill Cosby’s Brother And Mary Cosby’s Husband Share The Same First Name

Back in 2022, when people discovered that Bill Cosby’s brother and Mary Cosby’s husband bear the same first name, i.e., Richard, the rumors of them being related to one another spread like wildfire.

But the fans overlooked a small intriguing detail in their names.

Bill’s brother’s full name was Robert Leroy Cosby, and Mary’s husband’s full name was Robert C. Cosby.

Seen the difference yet.

Furthermore, while doing our research, we came across the obituary of the Late Mrs. Dolores Cosby, mother of Mary Cosby’s husband.

That obituary revealed that Robert C. Cosby had five brothers: Daniel, Thomas, Darrell, Anthony, and David.

There was no mention of Bill in the obituary.

Still, we were not convinced, so we dug deeper into Mary Cosby.
