Looking at Scotland's People, the genealogical website for the National Records of Scotland, and WikiTree, we can find an Edith Helen Nobbs, born in Russia around 1872, who married Charles John Robertson Milne in 1903 - the marriage certificate shows that Edith's mother was Agnes Fletcher Nobbs, nee Brown - hence we can assume that she is potentially the creator of the associated album.
Born Perthshire 1839; died Perthshire 1922
Charles McIntosh, sometimes known as ‘The Perthshire Naturalist’, was a postman whose rounds enabled him to observe and study the local flora and fauna of rural Perthshire. He was a member of the Perthshire Society of Natural Science and later the Cryptogamic Society of Scotland. He became friends with the young Beatrix Potter, then holidaying in the Dunkeld area, through their common interest in fungi, and helped improve the accuracy of her illustrations, taught her taxonomy and supplied live specimens to paint during the winter. McIntosh discovered thirteen species of fungus completely new to Britain and four new to science and some of his collection is now in the City of Perth museum. He contributed to FBW White’s ‘Fl. Perthshire’ published in1898.
