„Cassadale“(?)
Willing to bet that this is 'Carradale', after the village in Argyll.
The 1905 and 1915 valuation rolls list Wilhelm Kuhn as proprietor and occupier of 'The Linden', Craigcrook Road. In 1920 the proprietor was Russell Paton and the tenant and occupier was William Dods Hogg. There's no listing in 1895, so it is reasonable to suppose that it was built around 1900. The 1920 Valuation Roll lists Russell Paton as the proprietor of "
House The Linden 4 Craigcrook Road", parish of Cramond, Midlothian. (Later VRs list him as proprietor of a house called Stratheden, which seems to have been No 24).
Craigcrook Castle is still there.

This map
