Can anyone confirm if the Mary Ann Moore who was buried at Santan 27 Feb 1887 aged 24 is the one that I'm looking for?

My Mary Ann Moore was christened 1 Mar 1863 in Cleator, Cumberland, England. She was the eldest child of Sophia Cowle (also spelt Cowell or Cowll) and William Thomas Moore who married at Santan in 1861. It appears that they left her with Sophia's parents when they emigrated to Australia about 1864. In the 1871 census, Mary Ann was living with her grandparents John and Mary Cowle in Santan and appeared to be using their surname. In 1881 I believe she was probably the Mary Ann Moore who was a servant to the Goldthorpe family in Santan. After that I have no clue as to what happened to her apart from the possible death above. If she was buried above, was there an MI for her grave?

Thanks for your help.
