1871 Richard William Pugh b1865 Castletown staying with grandparents.
1881 William b 1863 Malew, Farm Servant at Arragon Moar.
1891Richard William b 1864 Isle of Man married to Sara Ann Clementsin Liverpool. Timber Labourer
1901William R b1862 Castletown living with Amelia F Hawkins in Liverpool.
What do you think?
