Dear Diana
The Ministry for Culture and Heritage looks after the graves of those who died during wartime, and there is no-one of the surname "Wallace" who died during wartime and who is buried at Sala Street cemetery. However, there may be Wallaces buried in the war veterans' section at Sala Street, and I am making enquiries on your behalf. Hopefully I will be able to get back to you by the end of this week about this. Regards,
Margaret Marks
