My grandfather Edward Charles Gannon-Leary (aka Ted) was London Irish, born in Chelsea of Irish parents. He died when I was eleven but I can still remember his idiomatic London English.

I can remember Dad telling me that Ted’s father had been in the 11th Hussars, also known as the “Cherry Pickers” which, to a child, sounded very romantic.

I knew little more about my Irish heritage at that stage but, after the death of my parents, I became interested in family history and began to explore this in more depth.

My grandfather Ted’s father was Patrick Joseph Leary and he married Elizabeth Gannon. The combining of the names came later and thereby lies a tale.

Patrick hailed from Cork and Elizabeth from Dublin. She came from a military family and her father John Gannon was a sergeant in the 8th (King’s Royal Irish) Hussars. He actually participated in the Charge of the Light Brigade – and survived. However, he died nine years later leaving a widow and three children, Elizabeth, Amelia, and John. Amelia was sent to the Royal Victoria Patriotic Asylum for Girls in Wandsworth and John junior to the Royal Military Asylum in Chelsea. Apparently, children who had lost their military fathers were treated as orphans even if they had mothers living and they were given charitable support. Elizabeth was lucky enough to escape institutionalisation as she was older and she went on to marry Patrick.

Patrick’s father had been a soldier, too, and Patrick had enlisted in the Grenadier Guards as a drummer boy but was invalided out in 1879. At this point, he adopted the surname Gannon and, using this, enlisted in the 11th Hussars in 1880.

He and Elizabeth had six children, including my grandfather Ted, the four oldest being born in Chelsea, the two youngest being born in Ballincollig, Cork and Templemichael, Longford. The Army Births and Baptisms records for the children are interesting as some of the children are registered twice, once under the name Gannon and again under the name Leary. It is clearly around this time that the names became interchangeable and later hyphenated.

Around 1891, Patrick Leary seems to have disappeared and resurfaced as James J Gannon, a sergeant in the Reserve Force Cavalry which is how he appears in the census of that year. He is given the attribution of head of the household and father of four of his children who are living with him at that point in Aldershot, Hants.

Family myth has it that Patrick emigrated to…
