Born in Woodhall as Rosemary Boffin during the Fell Winter of 1311, she met and married a young Baggins lad from Hobbiton by the name of Podo soon after her 35th birthday.
With Podo being a younger son from a less-prominent branch of the family, the newlyweds decided to combine their respective surnames and the Boggins family was created.
A year later, their son, Halson, was born.
Six years after Halson's birth, a second child, Prunella (or Nellie, for short), was born and their family was complete.

Halson ended up marrying a Bolger lass and they had two daughters together before the young couple drowned in a ferry accident on their way back from Buckland where they had been visiting relatives, leaving their daughters in the care of their grandmother.
Ten years later, an unknown plague swept through the Hobbiton-Bywater area, killing Podo's nephew, Porto, along with Porto's wife, Celandine, and orphaning their five children, who were then immediately adopted into the Boggins family.
