Andrew Patrick Walker was born on 22nd June 1922 at 63 Gardner Street in Partick.
His father, Thomas, had married Anna McDonald the previous year in Inverness. Thomas’s job was a mercantile clerk at the time, although later in life he was a company secretary.
Andrew had a younger brother John (“Jack) and Evelyn. By 1930, the family lived in Bearsden at 2 Lochend Crescent.
Could this be 10-year old Andrew at Bearsden Academy (Milngavie and Bearsden Herald 1st July 1932)?
Unfortunately the only other thing I can find about Andrew is the end of his life.
By 1941 he was a Leading Aircraftsman in the RAF, with 201 Squadron. They were based at Lough Erne and flew Sunderland flying boats on anti-submarine patrol in the Atlantic. This photo is from the Imperial War Museum website and shows a plane of 201 taking off from Lough Erne:
The following summarises an excellent page on the website irishaviation.com (link).
On 3rd December 1941 Andrew was onboard W3988, a Sunderland named PLUTO. During the patrol, the wireless stopped working. For reasons that are unclear the pilot then tried to land on the sea near a beach in County Clare around 6.30pm. All the crew evacuated and made it into dinghies in their Mae West life vests. In heavy seas they could not row the two miles to the shore, not stay in the boats. In addition, waves broke off a float on the plane and flipped it over. Only two of the crew of eleven survived; one of them wrote home to say the waves were forty feet high and he estimated it took three hours for him to get ashore. Andrew drowned and has no known grave and is commemorated on the Runnymede Memorial.
