R White I believe to be Rebecca White, Edward's spinster sister, who looked after one of the sons, Joseph, after Sarah died.
I don't believe it means she was the guardian.
Richard Hall was of Bramshott:

Sarah White died at Bramshott in 1843 and was buried there.
Merry, some time ago you found the death of Sarah for me after I had ordered a couple of incorrect certificates! I was very grateful.
