Looking for Ancestors of Sarah Ann Miller B 1874 IN Leatherhead Surrey

I am looking for ancestors of Sarah Ann Miller born 1874 in Leatherhead, Surrey. I am an ancestor of one of her brothers Walter Miller b. 11 May 1884 in Leatherhead, Surrey.

Her parents were Thomas Homewood Miller b. 1847 d.1917 and Mary Ann(Elsey) b.(abt) 1851 d.(abt)1930

I would love to get more information about her and maybe get a few answers. I have her listed in the 1901 Census living/working at 17 Rose Hill in Dorking, Surrey as a domestic cook. She was aged 27 and unmarried although I believe that it must have been very soon after the census(31 March 1901)that she married and went on to have many children.
I don't know for sure what her husbands' name was or where they lived after 1901.

Sarah Ann and Walter were the only 2 of 6 children to marry or have children, but there was another brother Martin that lived into his 30's.
