I have a GGrandfather named Henry Moncrief McLaren. His mother Mary Mckinnon McLaren died in 1855, that great year for certificates. Thanks to that I have her parents names. Her husband Neil McLaren is another matter altogether. I have the OPR of their marriage which tells nothing, and he only shows up on the 1841 Census at 31 years old. He has already died by the time of the 1851 Census. She was from Mull and I supposed that Neil McLaren was from there too.
Because he wasn't around that long I had almost forgotton him, but today when I looked on SP for him I found a Neil McLaren born in Argyll in 1810 in Ardchatten.

Googling for maps of Argyll, I found that Ardchattan was close to Mull.
The OPR record gives the name of the parents as Duncan Mclaren and Cathrine McIlreach. Neil's oldest son is named Duncan. This would follow the Scottish naming pattern.
I looked for possible brothers and sisters. I found three births that were possible, John, 1808, Jean. 1817 and Catherine, 1814, all born in Ardchattan.
My problem is that the parents of these three possible siblings are named Duncan McLaurin and Catherine Macilriach.

I have another problem, my GGrandfather Henry McLaren and his brother Duncan always spelled their names as McLaren.
I found the death(1876) Cert for one of the children of Duncan McLaurin and Catherine McIlreach, by name of John the oldest child and his name is spelt McLaurin, not McLaren.
My question is this: Are these the same family? Am I onto something, or is it just wishful thinking, hoping to get more information.
I would like anyones opinion on the matter and apologize for rambling on so long.
Regards
Sheila
P.S. Is Argyllshire considered the Highlands?
