Thank you, folks, for the swift replies.
I have the image of the 1871 census on my computer in my Scotland's People site. It is of West Greenock, the burgh of Greenock. The details are:
Alexander Maclean, 39, Grocer
Catherine Maclean, wife, 30
Catherine, dtr, 2
Christina, dtr, 5 mos
Christina ??, servant, 15
Lachlan McGillivray 25, nephew, Porter
Angus McGillivray 25, nephew, Student, Free Church Normal School.
The 2 children were born in Greenock, otherwise the rest in Kilfinichen, Argyll.
It is Lachlan and Angus I am really chasing.
The census form is legible, but nothing under any of these names is coming out on Ancestry for 1871.
I have a record of Lachlan in the 1891 census in Greenock in LDS - but again not on Ancestry.
Any ideas?
