I notice amongst the dead in the first world war was Norris Clague Cowin son of Thomas and Adela Janet Cowin.
The name suggests a Manx connection with a Clague/ Cowin union.
March 29 1825 saw a marriage between John Cowin and Margaret Clague in Braddan Isle of Man.

By 1841 at Wellington Gardens Douglas:-

John Cowin 38 Mariner
Margaret 30
John 15
William 14
Norris 12
David 9
Margaret 6
Esther 4
Alice 2

Thomas and Mary came later.
