According to the Index of Utah Pioneers compiled by the Sons of the Utah Pioneers
Urania Gregg came to Utah as a pioneer when she was 24.
She was married to Washington Perry McArthur in Scrubgrass
Township, Venango County, Pennsylvania on October 25, 1846, when she was 20 years old.
Very quickly the new family began the move west, as her first child,
Almeda Jennett McArthur was born just a few days
over a year later in 1847 in Fort Madison, Lee County, Iowa.
