Hi Ann,
Unfortunately I don't have much access to information and records from Lochcarron, although I do have some ancestors from there, including some side branches with McRaes. And in Glengarry I have nothing.
Your link to Gairloch is clearly Flora Chisholm. I assume you have her marriage to John McGregor, 28 JUL 1825 in Gairloch. It's in the OPR (in between two of my family members), but there's no additional info, except the reference to Melvaig.
If you are working on that Chisholm line, next door to John & Flora in 1841 you will find a brother of Flora, John Chisholm. Here's what I have from the census + additional info about that family:
John Chisholm 40 (He married Catherine Urquhart 11 JAN 1823 and later married Margaret MacKenzie 14 FEB 1831; he died 23 MAR 1885, aged 85)
Margaret Chisholm 35 (d 30 JUN 1895 in Melvaig, age 84)
Janet Chisholm 15 (Daughter of John's first wife, Catherine. She married John Urquhart and died 27 MAR 1864)
Alexander Chisholm 8 (Born 31 JAN 1832)
Roderick Chisholm 3 (Married Catherine McRae 20 JAN 1870, died 2 FEB 1925 in Melvaig)
The couple had at least 3 more children:
Kenneth: Apparently born 4 SEP 1834 (don't know why he doesn't appear in the 1841 census), married Isabella MacKenzie, he died 29 AUG 1911.
Margaret: Died young in 1857.
William: Born 24 NOV 1841
This Chisholm line was in Melvaig at least until the 1940's, maybe even until today!
Best luck,
Francisco
