Re: Unknown Death Causes 18th November 1918
I'm struggling with the first two and the last one, but I did find Davies.
285841 Alfred Wynn DAVIES - the National Probate Calendar records that he died at Dundee War Hospital (another entry has The War Hospital, Dundee, Angus).
After a bit of a struggle, the Statutory Deaths Register on the Scotland's People website records him as Alfred Winn Davis, which confused matters, and records that he died at 1.30 p.m. due to asthma, bronchitis and heart failure.
