New update Sarah was married in India before her marriage to Percy Cooke. She was originaly Sarah Clement (daug. of George Henry Clement). She married John Tremlett Trewman (or Truman) 21 May 1879 in India. He then died 10Oct 1879. So she was a widow in 1881 when she married Percy Cooke. I could not find any births from this first marriage. Hopefully this will make it easier to go back on her side.
