Looking for Langley at Nabowla Tasmania Australia

I am seeking information on WILLIAM LANGLEY, born c. 1878, died 05 April 1926 and buried at Nabowla. His wife, ELIZABETH LOUISA SMITH, was born c. 1875, and died 18 Jan. 1941 at Launceston and buried at Nabowla. She was the daughter of WILLIAM & ELIZA JANE SMITH. William & Elizabeth had (at least) 4 children: 2 sons & 2 daughters.The daughters married A. GRIFFITHS and W. BROADHURST (both of Targa). The sons were V.(possibly VERNON REUBEN of Launceston) and M. of Winnaleah.
