Hi there,
I've had another look at vol 4 but there are definitely no Maclennans. Mr Lawson tends to start with the earliest rental lists, sometimes back to 1799, and continues up to the the end of the 19th century or even later. (My mother, for example, who was born in North Uist in 1913, and is mentioned as moving to Greenock on her marriage).
One thing to point out is that the crofting books only deal with crofts, not with larger houses.
I'll have a look through the other volumes when I get a chance, but there are no indexes, so there's no guarantee I'll find them, as it's easy to skip over something.
I have, however found a reference to MacLennans in Bill Lawson's book, North Uist in History and Legend. It says a Donald Maclennan (Domhnall a Choibair) was a shepherd at Greinetobht and had come originally from Harris.
"The Maclennans had come from Tarasaigh in Harris, and when forced to leave there, had scattered, one to Fionnsbhagh in Harris, others to Airidh a Bhruaich in Lewis, and Donald to Greienetobht. Donald had died in 1889, but his son Donald took over as shepherd."
I'll have a look at the volume that includes Greinetobht tomorrow for you.
