I found my CD-ROM transcription of the 1881 census and 'walked' round Enumeration District 4.
Tudhopes Land is listed in Dundyvan Road between Hoggs Land and Neishes Land. Hoggs Land is also listed in Buchanan Street.
So I'd imagine that Hoggs Land was on the corner of Dundyvan Road and Buchanan Street, and that Tudhopes Land was next door to it, on Dundyvan Road. See
https://maps.nls.uk/geo/explore/#zoom=18.9&lat=55.85936&lon=-4.03699&layers=168&b=1However this doesn't agree with the newspaper report found by
hanes teulu that suggests that it was off Manse Road.
It has to be somewhere in the block surrounded by Manse Road, Bank Street, Dundyvan Road and Buchanan Street. Comparing this map with the older one I posted earlier suggests that it may have been built after the older map was surveyed in 1860; there are several blocks shown on the later map that were not these in 1860.
