We are on the right trail Linda with the Salen family I think.
Neil McIntyre married in Glasgow in 1865, a Lillias (lilly) Hannah McDonald. A blacksmith by trade age 28, therefore close to age in that 1841 census entry we now have.
Parents John McLucas, farmer, and Christina McIntyre, both deceased.
This is Neil in 1871 with new family - as transcribed not my spelling

Neel McLucas 34, Clacksmalk (blacksmith I assume!), b. Kilfonechan, Argyshire
Litty Hannah McLucas 33, Blacksmith Wife, b. Bonaw (?), Argyshire
Hugh McIntyre McLucas 5, b. Glasgow
Christina McLucas 3, b. Ardchattan,
Mary Ann McLucas 10 Months b. Ardchattan,
Address: Smithy, Ardchattan, Argyll
At a guess, first born son called after maternal grandfather perhaps.
