John's brothers were too young to be called up.
John also had several other relatives in Teesdale who also served in the war (see separate entries on the database): William Porter (of Cotherstone, father to Ernest and Joseph); Adam Bainbridge and John Joseph Bainbridge (of Forest and Frith); Frederick Porter and John Henry Porter (of Kinninvie Marwood); Arthur Edwin Raine and William Stanley Raine (of Middleton in Teesdale); Herbert Dennis Raine, Edward Richard Raine and George McKenzie Raine (from Low Selset - Lunedale); Arthur Henry (Harry) from Ingelton; and Edgar Heslop (from Marwood).
