Hi Monica, Annette and Maiden Stone!
Thank you all so much!
Yes brother Patrick registered his death.
His birthday is on the death cert but also his army record backs this up
Yes I know Patrick is his brother from the death cert but also this corresponds with the Irish census from 1911.
They also lived together in Rowton House in St Pancras, London together in the 1920s from 1923 to 1926/7
I can find Patrick in Watford, Herts with wife Olive in the 1939 census right where my Grandfather was reported to be when meeting my Grandmother and my father was born 10 years later.
Patrick and Olive also married in Watford the same year that my father was born in 1949.
Interestingly the date of birth of Patrick in the 1939 census is the wrong year.
He was born 10 August 1900 but on the 1939 census he is listed as 10 August 1902 which of course was the year my grandfather was born not Patrick.
I have birth registrations and baptismal records for all of my grandfathers siblings to back up these dates.
Can anyone point me in the right direction of looking for WW2 records of soldiers as I am finding these much harder to find online unlike WW1?
