Out of interest, I put the word Gargell into a newspaper search for Lanarkshire.
It produced a few results but, one may be of interest
Glasgow Herald Dated 13 Jan 1875 ( more than 40 yrs after the 1828 birth in the OP)
Heading: Notes On Miners Housing (11) by our own correspondent.
Ot was obviously No 11 of an ongoing report into the conditions of Miners Housing.
This particular report centred on a one day tour made by the journalist Mon 11 Jan 1875:
He picked up an "engine" from Coatbridge which allowed him to visit several places during daylight hours.
He visited, Gargell, Gartloss, Rosehall,Greenend, Faskin, and Woodhall.
He didn't think the conditions of the miners houses were too bad but, the water supply was defective and clearly contaminated.
He made a reporters joke about Gargell.
Indicating that he would not be able to direct you there with any degree on confidence!
The only way to reach it is to pass through the town of Gartsherrie ( mentioned the name Baird was a force to be reckoned with ).
"Strike across an uneven country with very bad roads, and at length tumbled out at Gargell."
He then describes it as a extremely small unpleasant place.
A single row of 11 houses also owned by Messrs Baird.
Two had slate roofs, the rest were primitive thatch.
An open drain runs through the gardens and empties into an underground sewer.
The water supply was the biggest issue here too.
The residents preferred to travel to the railway station to collect clean water rather than use the supply at Gargell
