Hi Mum Mum
Thanks for your input. I believe my friend has his service record as that is where some of the information she knows about him has come from. Otherwise yes I would also suggest the same to her.
And yes I believe all concerned are deceased. It is a difficult one as there are so many ways information could be incorrect or changed - whether it is dates, first names, last names, parents names etc so it will be a process of elimination.
Many thanks
Carolyn
