Hi Louise,
The burial records for Cambusnethan cemetery state that "Robert A Macrae, abode Newmains, aged 10 months, was interred in lair number 1745 of section E on 13th September 1909. The lair owner was William James Armstrong, engineman. Loudon's Land, Main St, Newmains.
Robert's parents are listed as Archibald Macrae and Susan Armstrong.
There were a few Armstrong families around Newmains, Joseph Armstrong and Margaret Johnston. Adam Armstrong and Margaret Thomson. Joseph Armstrong and Margaret Donald.
Main Street Newmains later became Manse Road. It is a continuation of Cambusnethan Street. All along this street were single-storey buildings, Loudon's Land being one of them. Another was Bryson's Land where my great-grandfather was born, I have a photograph of it (too large to post, sorry) it was a long row with about 4 houses on the front and a similar 4 at the back.
My grandmother's uncle owned and lived in a two storey tenement building consisting of 2 houses on the ground floor and 2 upstairs (flats or apartments - whatever you like to call them nowadays). That building was called Paterson's Land and it was in Dalziel Street Motherwell. It was still in the family until it was demolished in the 1960s but by then the term "land" had fallen into disuse and it was known as Paterson's building.
Good luck with your research.
Lodger.
