1 William ‘Willie’ Cochrane, gardener, was Inhabitant Occupier not rated at Whitmuirhall, Selkirk [1921 Valuation Roll, VR011700009-/333, Selkirk County, page 333 of 611]
2 Straker Squire or Straker-Squire Ltd., also Brazil, Straker (1901-1927), motor manufacturer; the Muir & Graham partnership had run their Straker Squire since at least early 1919
3 Janet Louisa Heard (1921-), daughter of Walter Heard, general labourer, and May Heard née Avery, was extremely ill with Diphtheria; the implication here is that she was at the Infectious Diseases Hospital by this time though Dr Muir had previously been seeing her at home at Castle Street, Selkirk
4 There was a nasty outbreak of Diphtheria and Scarlet Fever which had been running in Selkirk since the summer of 1921 and continued into 1922
