I had a William Nicol as the main householder at the time, but renting and relations are not impossible, so I tried to find links but couldn't get any. In the end it was back to searching the 1841 census, which sadly gives Mr Hime at 6 Abercromby Terrace, an amalgamation of the two. But never necessarily trust a newspaper report alone.
Other interesting news comes from research into Mr William Lawson, one of the prime movers in the creation and landowning of the Square. As it turns out he was a relation of the Liverpool architect Peter Ellis, who I'd always kept an eye out for in relation to the square, as there are some links between him and Culshaws and other firms associated with building in Abercromby. It isn't a close family tie, and is through Ellis's wife, but its interesting that Lawson forgets his actual relation's forename, only referring to her as wife of Peter Ellis, with whom he's clearly familiar. I'll post if I get any further on this.
