Born in 1893 in Carnforth, Frank was the Son of Lancelot and Ellen Marcy Jackson, of The Lodge, Yealand Conyers, Carnforth, Lancs.

In 1911, he was listed in the census as an apprentice gardener living at “the bungalow” Bailrigg. Frank had an older brother, Lancelot Henry and two sisters Mary Isabel and Alice Ellen. He also had a younger brother Edward.

Frank enlisted in Lancaster (he was a pre-war Territorial for four years) and arrived in France on 14 Feb 1915 with the 1/5th Battalion King's Own.

At the time of Corporal Jackson’s death, the 1/5th were in the Ypres Salient as part of the 83rd brigade 28th Division. A full account of all the actions in which he served is in the 1/5th Battalion war history, which is available from the Kings Own regimental museum. 

The Battalion history published in 1921 (Hodgkinson) remarks of the 8th to 10 May: “On May 8th, the day the Colonel was wounded, the Battalion was ordered to GHQ lines to support. We lost some of B Company from a shell as the men fell in and were heavily shelled in GHQ lines until ordered to advance to retake lost trenches and to take on the remnants of the 2nd Battalion Kings Own and the Monmouths. The advance took place under heavy shell fire and enfilade fire from machine guns on the Polijze road. A line was occupied 1,200 yards in front of the GHQ lines but a bayonet charge at 8pm failed to carry the advance further. Five Officers in addition to the Colonel were wounded that day…total casualties for the day were 1 officer killed and 6 wounded, 15 NCO’s and men killed and 96 wounded. 10 NCO’s and men died of wounds later”

Franks obituary in the Lancaster Observer dated 21 May 1915, page 3, records the Memorial service at Galgate C of E Church conducted by the Rev F Coleman. “At the commencement of the service the organist played “O rest in the Lord” whilst the choir sang the 39th Psalm. At the conclusion, the organist played the dead march in Saul” (This obituary and the above photo of Frank Jackson appeared in the Lancaster Observer and Morecambe Chronicle of Friday 21 May 1915).

Frank was awarded the 1914-15 star, British War Medal and Victory Medal.

Franks original Grave Marker cross was bought back from Belgium by his Parents and it was placed in the Churchyard of St Johns church near the west window until 1967, when it was bought inside the church to help preserve it.
