Hi, thanks for that.
I looked in to these a couple of years ago and worked out that the family of five with father Alex being a coppersmith, from the Family Search website I think Catherine was Catherine MacDonald and they were married in 1832 but that doesn't work out for this family as their children were all born before 1832, so this can't be right. There is also a Catherine Ross who married an Alexander Fraser in Inverness 1 June 1821. But I can't find a marriage between Fraser and Cameron.
A few years ago I found an IGI record for a Margaret Fraser, born 9.7.1832 Bap 16.7.1832 at inverness with parents Alexander Fraser and Margaret Cameron. There is also a family on the 1841 census with father Alex as a shoemaker, wife Margaret and 7 children including a Margaret aged 10, so this is probably the Margaret on the IGI individual record so not mine.
On the 1851 census I found a Catherine Fraser aged 51 shown as wife with a Donald McPherson, a pensioner in Inverness. There was a marriage for them in Jan 1842, so not sure why she was on as Fraser. With them were his stepson Alexander Fraser 23 and Margaret 18 stepdaughter shown as a Flesher's daughter. A flesher seems to be a butcher. This could be the first family you found at Shoe Lane. Does flesher's daughter refer to her stepfather as being butcher or her biological father.
