There is a reference to a Turnbull at this address in 1849, but then no further mention until 1857. It is not clear whether the earlier person is the same as, or related to, the present one. The cdv above is similar in design to others (by Stuart , for example) dated to 1862. The crest quaintly shows a turning, or turned, bull, a fancy returned to in later years. The remark at the top of the back about Arrochar is not understandable.
