Rosie Cotton (AU)

14
Rose Cotton was born in the year 1384 by Shire Reckoning, the second child and first daughter of Tolman Cotton and Lily Brown. The Cotton family lived in a farm on the South Lane, which was fairly close to Bywater. Not much of her youth is known, except that she has older twin brother Wilcome "Jolly" (April 26 TA 2884) and a younger brother Bowman "Nick" Cotton (June 29 TA 2886), younger twin sister Cynthia and younger brother Rhodes Cottons (October 28 T.A. 2980) - frequently swam in the Bywater Pool with the children of the Gamgee family, to which the Cottons were close.
Rosie was still fond of Sam when both grew to adulthood, and when he announced he'd be going with Frodo Baggins to Crickhollow, she did not like it.[5] Even though everyone had given up hope of seeing Sam - or any of the other Hobbits - back, she waited patiently. Since the Spring of T.A. 3019, she had expected Sam to return.
At the time, Ruffian rule over the Shire had lasted some three months, having started earlier that year. Old Tom Cotton had been itching to get his hands on them, but he refrained from doing so as he had his wife and Rosie to look after. Rosie was relieved to find Sam on the doorstep on November 2.
Rosie and her mother tended to Sam, Frodo and several others that night, as they prepared to drive out the Ruffians. With shining eyes and a smile on her face she heard Frodo tell of Sam's adventure and fame abroad.[7] Sam and Frodo lived with the Cottons until Bagshot Row and Bag End were restored, the following Spring. Sam later joined Frodo in Bag End, but was torn in two - he wanted to stay loyal to Frodo, as well as marry Rosie.
Frodo solved this problem by telling Sam that he and Rosie would both be welcome to live with him at Bag End after the wedding. Sam and Rosie married on May 1, T.A. 3020, and moved into Bag End.
