"At the invitation of the Greek Prime Minister, M.Venizelos, Salonika (now Thessalonika) was occupied by three French Divisions and the 10th (Irish) Division from Gallipoli in October 1915. Other French and Commonwealth forces landed during the year and in the summer of 1916, they were joined by Russian and Italian troops. In August 1916, a Greek revolution broke out at Salonika, with the result that the Greek national army came into the war on the Allied side.
The town was the base of the British Salonika Force and it contained, from time to time, eighteen general and stationary hospitals. Three of these hospitals were Canadian, although there were no other Canadian units in the force.
The earliest Commonwealth burials took place in the local Protestant and Roman Catholic cemeteries. Salonika (Lembet Road) Military Cemetery (formerly known as the Anglo-French Military Cemetery) was begun in November 1915 and Commonwealth, French, Serbian, Italian and Russian sections were formed. The Commonwealth section remained in use until October 1918, although from the beginning of 1917, burials were also made in Mikra British Cemetery. After the Armistice, some graves were brought in from other cemeteries in Macedonia, Albania and from Scala Cemetery, near Cassivita, on the island of Thasos.
There are now 1,648 Commonwealth servicemen of the First World War buried or commemorated in this cemetery. The Commonwealth plot also contains 45 Bulgarian and one Serbian war graves."

Christoper is named on the plague on Cinderford's War Memorial, see http://forum.forest-of-dean.net/index.php?mode=thread&id=43700.
He is within this FoD site's WW1 Servicemen database, as are other Cinderford Malsoms such as Charles & Ernest, his brothers perhaps ?.

Searching the BNA site gives this extensive Roll of Honour article;

Gloucester Journal of Saturday 15th July 1916;

"FORESTERS’ ROLL OF HONOUR
The recent casualty lists have contained the names of several more Forest boys who have fallen in the great war. Official information has been received by Mr. and Mrs. Levi Malsom. Bilson Green, Cinderford, of the death of their son, Pte. Christopher Malsom (26), which occurred as tbe result of a bombing accident on June 16th. The young man was a collier at Ligbtmoor, and latterly worked in South Wales, where on the outbreak of war he joined the South Wales Borderers. He was selected from the Battalion to be a grenadier, so Captain John England writes to the distressed parents, and was looked upon as one of the most reliable bombers.
News of the death of Pte. Theo Gabb. son of Mr. William Gabb, has been received in Cinderford. The War Office had notified Mr. Gabb that his son was missing, and later letter has come from an officer of the battalion saying it was his sad dutv to report the expected death of the soldier in question. “He was,” the writer says, "carrying out some very gallant work and was badly wounded. Every night since the accident search had been made, but no trace of the brave bugler was found.” The loss of this son is particularly sad, as on September 25th, 1915, another son, Dennis, of the Gloucesters, lost bis life.
The news of a double bereavement of the family of Mr. and Mrs. George Edwards, of Buckshaft, Ruspidge, has also fallen heavily upon the whole neighbourhood, when a letter came announcing that two sons of Mr. and Mrs. Edwards had been killed in action. Two comrades sent the distressing news, and said that Alec (who was nearly 21) was killed by a bullet through the head. The following evening his brother Arthur also met his death through a piece of shrapnel striking his bend. Both deaths were instantaneous. Both soldiers were highly respected in the district, being faithful members of the Wesleyan Sunday School and Band of Hope, also members of the Rechabite Order. The younger boy worked at Lightmoor, and the elder was employed in forestry.
A letter from the captain has been received by Mrs Cooper, Bilson Green, telling her that her son, Pte. William John Cooper, who enlisted on June 7th, 1915, in the Gloucestershire Regiment, was struck down while executing a brilliant piece of work. He did his duty well, and died as a Britisher. The officer expressed the hope that Mrs. Cooper would be given strength to bear the blow, knowing that his life was not wasted, but given to his country to leave it a better place than he found it.
Mrs. Hancock. of the Bell Inn. Littledean, received intimation that her brother, Pte. Owen Williams, had been killed in action, but a further report states he is missing.
We also learn than Pte. Harry Thynne. St. Briavels, of the Gloucestershire Regiment, is reported wounded in the arm, and is in hospital at Chatham. Pte. Harold Havward, of the A.S.C.. is also badlv wounded in the eyes, and is being treated at Leeds."

Hi again David,
am I correct in thinking you have access to the British Newspapers Archive ?. If you do, then I expect you've already seen that Levi was in court on 6th February 1892. The article states he was lodging with his sister Eliza & her husband Thos Cooper, they had a rather unpleasant argument about rents, and mother Elizabeth gave corroborative evidence.

As with the earlier items, it's clear that these years were not kind to the unfortunate Malson family, the same "Malsom, Drybrook" search also found this;

Gloucester Journal - Saturday 28 September 1878
"Littledean Police Court.
Levi Malsom, a boy, of Drybrook, was charged with stealing a tin of preserved fruit, value 1s. 3d., the property of Emanuel Smith, grocer. The prisoner, who could not say his age, but whose age was subsequently stated to be sixteen years, and who could not read or write, was sent to prison for seven days."

The same search also finds a few mentions c1880-1890 of an Oliver Malsom at the Petty Sessions, who enjoyed his beer, much like some of my ancestors who lived in the same Ruardean Hill/Drybrook area.
I expect you've already seen this old thread about Oliver, born abt 1850, sorry for not spotting it sooner.
http://forum.forest-of-dean.net/index.php?id=22180

There is also an extensive article concerning the 25th January 1913 Inquest at Gloucester of Charles Malsom Bannister, 49, a mason of Harry Hill, who died after an accident while working at Cannop Colliery; looks like one of the family ?.
Hard to be sure given the name spelling variations, but I cannot find this Inquest within this site's database. I do see that Levi and George are among various Malsoms attending Drybrook area Inquests within this site's records. The newspapers also carry this Inquest in which Levi was a key witness, December 1898.

Hoping this helps you with your researches, Jeff.
