I think that this is the first 1841 family in 1851 Note father is William:
Achonachie, Urray, Ross & Cromarty
William mcGregor, 65, farmer,employing 5 men, b. Gairloch
Hellen, 51
Mary, d 20
Alexr, s, 17
Margaret, d 15,
George, 13
Williamina, d,10
William, s 6
Cristina Cameron, visitor, 28, excise officer's wife, (a Christina Mcgregor married a John Cameron in Stornoway in 1843)
William Cameron, vistor, 5, ex off, son, b. Urray
John Cameron, 1 month , -do-, b. Urray
All above b. Lewis unless stated otherwise, I think the Cristina, aged 28, would be the Christina, aged 18 in 1841
