Mormon TikToker From World's Largest Polygamous Family Opens Up About Having 150 Siblings

For anyone curious to know what growing up with 150 siblings is like, one young Momon musician from one of the largest polygamous families in the world offered his insight in a series of TikTok videos on his channel.

Murray Blackmore is a music producer who was raised Mormon in the "sheltered cult" community of Bountiful, Canada along with his 150 brothers and sisters.

His father, Winston Blackmore, 64, is the leader of the Fundamentalist Church of Jesus Christ of Latter-Day Saints, and he has 27 wives.

Murray has over a million followers on TikTok, where he shares his unorthodox family experiences that come with living with his "litter" of siblings.

In the video, he said there is a "birthday party every 2 weeks," that he has "at least 8+ people" his same age to grow up with, and that "sibling rivalry can be with gangs of people."

People fascinated with his family commented with their reactions.

In a video explaining what it's like to have 150 siblings, Murray responded to an inquiry if he knew all the names of his brothers and sisters.

"I know all their names. But I could not name them all off the top of my head."

In a separate video, Murray said he was born in 2001 along with 11 siblings the same year. From that year, he has three brothers and nine sisters, and all their names begin with M.

He also confirmed the naming rule applied to other age groups as well.

"Yes there are Rs Ns As Os Js etc.", he said.

When one commenter asked if he had "friend groups" or more like "sibling groups," Murray said:

"So, growing up, we all went to school together. We had this private school, called Mormon Hills School, where it was just siblings or people that you were related to."

He added:

"It was never a thing to have a crush on anybody because of the fact that we were all related."

"It's just like with regular friends, if you have a common bond with them you're more likely to create a circle or a group. The only difference [is] that you all live together and you're all siblings."

When asked if he still gets new siblings every year, Murray said, "As of now, yes," adding, "there's been news of another pregnancy, and my sibling numbers will rise to 151."

"I don't know if this is the last, I couldn't tell you. But with what's left of my parents, they are still having kids."

The TikTok videos on his page address many facts about being born into a cult and growing up with such a large family.

Life with the Blackmore family is further explored through documentaries on YouTube, which he showed thumbnails of in the clip, below.

With plenty of people prone to making assumptions about growing up in a polygamous family, Murray encouraged those who are curious about his life with one father, 27 stepmoms, and 150 siblings, to watch the YouTube documentaries and to "follow from my perspective."

"It's been 'normal' for me my entire life," he proclaimed in another video.

Regarding his stance on polygamy, Murray said he "personally wouldn't choose that lifestyle."

"But many of my siblings have, and I support their decisions to be happy."
