Mitchell of England

Hi my great grandfather was Thomas Shilston Mitchell, born in 1867. His parents were John Woodley Mitchell (b.1842) and Mary Shilston. Thomas Shilston Mitchell married Mary Hewett (1869- 1915)I am looking for Mary's parents. I am also looking for Edward Henry Hewett's (1938-1920) parents. If anyone can help I would really appreciate it. Thank you
