Kylie,
In 1891 her father, Augustus was in Stoke Newington, London. He was 38, waiter inn, born Lynn, Norfolk. His new wife is Sarah age 30 born Aldgate, London.
I noticed from the 1891 census that Carrie & brother, Percy were with their relatives in Slaugham, Sussex.
In 1901 her brother, Percy is a boarder with a Henry & Eliza Shinbrole, florist gardener at Church Cottage, Church Rd, Woking, Guildford, Sry. RG13/597/134/23.
Percy GRIFFIN boarder single 22 carter on farm b. Woking Sry.
Of Carrie in 1901 there is no sign & I've tried all sorts of tricks to find her

I did find a possible marriage on FreeBMD;
Catherine B. GRIFFIN married Arthur J. Johnson, Southwark Sep. Q 1912 (1d 121) She would have been about 30, so very plausible.
Do you have the day & month of her 1881 baptism?
