Text on the card reads: "Got back to the old place once again. Hoping this will find out all well. What do you think of our Tower Your Old Chum Andrew". The card itself was made by J&M - I assume printers, and it was part of the "Caledonia Series."
There must have been a number of people living at 9 Roseneath Terrace at that time. Susannah (the mother), Jack, William, and Bella (all siblings) are noted as living here in postcards to this point. Annie, the youngest daughter, seems to have been a maid for someone, and she sent cards from Gourock and Dunoon which seem to lead to this conclusion. I'm not sure if Susannah's husband, John, the father of these 5 children was there, but I assume he was as he and she eventually moved to Vancouver and he died there in 1940. Son Alexander was the oldest and may well have already moved to Vancouver by October, 1909. By 1911, Jack, William, Alex, and his wife, Matilda, were all living in Vancouver. (I can find nothing of Matilda to find out her maiden name or where and when she and Alex were married - but she did die on September 17, 1920 - September 17th is my birthday, by coincidence).
The front of the postcard shows the tower in Tain that is attached to the court building - if you look at the last postcard, the base of the tower can be seen on the left hand side. The courthouse was built in 1849 with additions in 1873. The tower itself, however, is "ancient" (no date found) with it's bell being made in Holland in 1616 - it was formerly part of a prison. If you look at the pictures, you can see the difference in the masonry. More information on the history of the town can be found here.
