Hi Cillia

My William Semmens was born in Cornwall 2/9/1849. His children were William James Semmens (born England, 7/1/1873) Elizaan (born 17/7/1870) and John Thomas Gilbart Semmens (born 22/10/1876).
William James Semmens' children were : Stanley Semmens (born Camborne, England, 1895, died Cornwall 1971),
brothers William Ernest Semmens, Albert Semmens + George Henry Semmens.
I am not sure at this stage how they are connected to your William Semmens?
