I hope members of the Black Watch Regiment don't mind me posting this from the Royal Irish Fusiliers Museum on the off chance that some one may have information on the Webster family.

Armagh casualty of WW1 to receive long awaited memorial:

On the 14th March 2012 Pte Thomas Webster was accepted as a war casualty by the MOD and Commonwealth War Graves Commission.

His original burial place in St Marks, Armagh, cannot be found and so the CWGC will erect a dedicated headstone within the Churchyard in due course.

Now volunteers at the Royal Irish Fusiliers Museum, guided by volunteer researcher Joe Center, are hoping to find relatives of Pte Webster, so they can attend the dedication ceremony.

If you or someone you know is related to Pte Webster, please get in touch with Mr Center via the museum email: fusiliersmuseum@yahoo.co.uk or telephone 3752 2911

Thomas Webster was born in Armagh on the 9th July 1893, the son of Thomas and Maggie Webster of 2 Linen Hall Street, Armagh.

He was baptised at St Marks Parish Church on 4th February 1894.
In the 1901 Census the family are living at 2 Callan Street, Armagh.
At this time, Thomas had two younger siblings, Maggie and Robert.
By 1911 the family, now with four children, are living at 36 Callan Street.

Thomas enlisted into the 4th Special Reserve Battalion of the Royal Irish Rifles on 16th September 1910 stating his trade as a tailor and within a few months he decided to join the Regular Royal Irish Rifles, on 9th March 1911.

His service took him from Dover in 1911 to India in 1913, where he was stationed with the 1st Battalion of the Royal Irish Rifles until the outbreak of the First World War.
Thus began the move back to the UK and then France in September 1914 aboard the HT Dilwara.

This journey proved arduous for Thomas as he developed a cough and fever which rendered him no longer physically fit for war service, due to tuberculosis. He was discharged from the army on 9th February 1915.

He returned to his family home in Armagh but died at the Armagh Workhouse, which was then used as a Military Hospital, on the 9th May 1915.

His brother Robert of the 9th Bn Royal Irish Fusiliers is also buried in St Marks, grave unknown, he also was discharged physically unfit and he will be remembered on the new headstone.
