Rhian(VVF029) was born in the Vivian group on September 21, 1998. Her mother was Vivian and her father was VYM009 a rover from the Young Ones. Rhian only had one other litter-mate, a brother named Humphry(VVM028). Both of them survived to adulthood. During her time as a subordinate female Rhian was never evicted. In February 2000 Rhian mated with a roving male named Snert and fell pregnant. However only a month later Rhian's mother Vivian died. The cause of her death was never discovered. Rhian was the oldest living female in the group, so she quickly became the new dominant female.
