Thanks to Patrickw I have contacted the Barracks and found out that they do an Ancestry request for £15. they will send you a form to fill in any detailsyou already know & then they do the rest. Personally I think that"s quite good value. Only downside is it takes between 3 & 5 months due to the demand for this service. Also the Barracks Museum is open to the Public, so when the weather improves,I intend visiting. Thanks so much to everyone who replied to my original query,will let you know how I go on
