Peter Patrick (Patsie) Costello was born in Flint on 14th November, 1896 in Flint and baptised on 29th November, 1896 at St Mary’s Catholic Church, Flint. He was the sixth of nine children to Patrick Costello and Ellen (McManus) and the brother of Private William Costello.
In Patsie’s early years the family were living at 35, Mumforth Street, before moving to No. 59.
His father, Patrick, was born in Salford, Lancashire and died on 16th March, 1910, aged 50, at his residence, 45, Mumforth Street, Flint, after an illness of only a few days, and buried in Pantasaph Cemetery. He was employed as an ironworker and had previously worked as a caustic maker, probably at the British Glanzstoff Chemical Works, Flint.
The following year Mrs Costello married John Mears Logan (1862–1946)
At Flint Borough Sessions, on Wednesday 6th December, 1911, George Jones, ironworker, 57, Mumforth Street, was summoned for using threats to Ellen Logan, a married woman, on 3rd November. Mr T W Hughes appeared for Mrs Logan and said the parties lived next door to one another and Mr Jones was continually annoying her. Mrs Logan said she was in bed on the night in question when she heard Mr Jones shouting to her from the street. He threatened to kill her, called her Mrs Maybrick, and used a great deal of abusive language, charging her with all sorts of immorality. On the following day he repeated his conduct, saying she had poisoned her husband and had her children heavily insured for the same purpose.
Mr Jones said Mrs Logan drew all the bother on herself; she was the aggressor. Police Constable Hughes spoke to being called to the house and being insulted by Mr Jones. Mr Jones’s wife said Mrs Logan was always carrying on with her ever since Mrs Logan’s son was locked up. Mr Jones and his wife both said he was at work all the night of 3rd November. He went next morning and told her what he thought of her. The Mayor described the proceedings as discreditable, and said both would be bound over for six months. Mrs Logan strongly objected at first, but was ultimately persuaded to abide by the decision of the Bench.
Patsie was employed at the Hawarden Bridge Ironworks, Shotton and was unmarried.
He enlisted in Flint on 7th September, 1914 and landed at Boulogne, France on 27th September, 1915.
Private Costello was killed in action in France on the 16th August, 1916. He has no known grave but is commemorated on the Thiepval Memorial, Somme, France, on Pier and Face 4A. He is remembered on two war memorials: Flint Town and St Mary’s Catholic Church, Flint, and was awarded the 1914–15 Star, British War Medal and Victory Medal. He is also commemorated on the North Wales Heroes’ Memorial Arch, Bangor.
His mother, who was born in St Asaph, died 8th January, 1922, aged 57, and was buried with her first husband Patrick.
