Hello Elaine
With ref to your relation Laurence/Lawrence Henry Mangan.
I have had a look at the 250 plus medal rolls for the Leinster Regiment pertaining to the Queens South Africa medal. If my eyes didn't deceive me after looking at all the regimental numbers and surnames beginning with M. I'm afraid I didn't find a match for 6793 Private L Mangan.
However, it is possible he did serve during the Boer War. His regimental number 6793 would have had him joining the Leinster Regiment sometime in the 1st quarter of 1902. The medal rolls cover 1st, 2nd,3rd,and 4th battalions who were eligible for a QSA medal.
I also checked the Leinster milita battalion who were attached to a Lancashire regiment, as I thought your relation had a Lancashire connection. Alas, still no match. The Irish 1901 census has a Laurence Mangan aged 17 working as a Farm Servant. The 1911 census has a 28 year old Laurence working for a different family as a servant. His WW1 medal information records him as serving in the 2nd Battalion Leinster Regiment as a Private 6793, along with his time in the Army Service Corps regimental number 40643. Ancestry has a few family trees dedicated to Laurence and the image of him serving as a Corporal looking very proud in his home guard uniform which I believe you mentioned in your original post? I hope you don't mind? I have posted the image and If you look closely at his medal ribbons, although the detail is unclear. I believe the ribbon far left maybe a QSA alongside his WW1 trio ribbons. I maybe wrong and I would welcome fellow forum members to clarify. There is another possibility, Laurence may have used a false name when he attested for the Leinster regiment. It wasn't unusual for recruits to use a mothers maiden name. If at some point you could provide any additional clues, we may get lucky and discover if Private L Mangan did serve in the later stage of the Anglo Boer War.
