He was born on September 25, 1840 near Kingston, Adams County, Illinois. His mother died when he was born and subsequently was raised by his father's two sisters, Mary Polly Brown [1789] and Nancy Brown (Newbury Critchlow) [1792]. These sisters lived with Captain Brown's family. When his father's family moved to Utah in 1848, eight year old Moroni did not make the journey with them.
Erold Wiscombe writes that Mary Polly and Nancy went to Illinois with their younger brother Daniel Brown in 1831, along with Daniel's two brothers-in-law, John Stephens and Alexander Stephens, and Daniels' nephew, Homer Jackson, son of their oldest sister Susan Brown Jackson. Daniel's wife, Elizabeth Stephens, is the sister of Moroni's mother, Martha Stephens.
The Brown family arrived in Illinois about the time that the Mormons were being driven from Missouri and settling in Illinois. Due to the missionary efforts of Jacob Foutz and others both Brown families, Daniel's and his brother, James's, joined the Church of Jesus Christ of Latter-day Saints, along with Mary Polly and Nancy Brown and John Stephens and Alexander Stephens.
After the death of her husband, Alexander Stephens in 1824, Grandmother Mary Daley Stephens also brought her large family of eleven children to Illinois.
Mary Polly Brown, Nancy Brown, and Moroni Brown continued to live near Daniel Brown for some time. When the Mormons were driven from Nauvoo, Daniel decided it would be best to try to follow them. He took his son James Stephens Brown 18 yrs, his brother-in-law Alexander Stephens, and the two sisters Mary Polly and Nancy, with the young child Moroni Brown, and left them out in Iowa with instructions to plant a garden while he went back to Brown County, Illinois to reap the harvest and sell the farm. He would then bring the rest of the family and they would all follow the church as best as they could until a resting place was found. The place they were staying at was one of the headwaters of the Grand River in Iowa. There was a large group of Mormon emigrants also camped there.
Soon after Daniel left for Illinois word came from Washington D.C. that the President wanted 500 volunteers from the Mormon emigrants to form a battalion to fight in the Mexican War. The Alexander Stephens 33 yrs, Alexander Brown 20yrs, Jesse Sowell Brown 18 yrs, and James Brown Jr. 45 yrs, all enlisted. When Daniel returned he was very much upset for he felt that Brigham Young had no right to take his 16 year old boy, Wilson Brown, away from him while he was yet under Daniel's protection without Daniel's permission.
