I read a wee book about the Powder Mill at Clachaig but by memory is failing ... I am going back to the library today ... if it is still there I will look and see what it states as the owner Sheriff bought the land from. 

I have not looked further into hte Curries ... difficult to go back here before mid 1700's without looking at all the sassines.

The Bornws however I studied.  There is indeed a strange name change from McGilmichael/McIldonie etc into Brown starting at the very start of the OPR's ... sometimes it reverts back which makes it difficulf for anybody with the name Brown to research their ancestors here. 

At present I am studying the Harkness family.  Thomas Harkness was not alone ... there was also a John and a Margaret Harkness who came here probably late 1740's early 1750

Please be more specific in your questions ...

It seems likely Finlay Brown and Mary Turner also had a son Peter as on 16 December 1816 in Inverchaolain you have a Peter Brown of Brackleybeg marrying a Flora McMillan of the parish of Kilcalmonel.  Unfortunately, I cannot find any of the children born to them between 1816 and 1832. 
The 1841 census gives them at Inverchaolain at Portlamont
Address: Portlamont
    BROWN   Peter   M   54   Ag.Lab.    Argyllshire       
    BROWN   Flora   F   46       Argyllshire       
    BROWN   Archibald   M   15   Ag.Lab.    Argyllshire       
    BROWN   Peter   M   12   Ag.Lab.    Argyllshire       
    BROWN   Margaret   F   9       Argyllshire       
    BROWN   Flora   F   7       Argyllshire       
    BROWN   Jane   F   2       Argyllshire   

On 9 October 1847 an Isabel Brown at Portlamont marries a Peter Rankin.  Must be one of the children born to them in the missing period of 1816 - 1816

daughter Margaret and son John McLean lives with sister Isobel Brown at in 1841
Address: Brackleymore
    WHITE   Donald   M   45   Farmer    Argyllshire       
    BROWN   Isabel   F   30       Argyllshire       
    MCLEAN   Margaret   F   8       Argyllshire       
    MCLEAN   John   M   12   Male Servant    Argyllshire       
    WIER   Catherine   F   14   Fem.Servant    Argyllshire

I just discovered Isobel married Donald white on 21 March 1833 at Inverchaolain: Donald White in Knockdow with Isabel Brown in Brackley

Mary Turner is still alive in 1841and living with son Alexander at Brackleybeg which is clear from the 1841 census of Inverchaolain

Address: Brackley Beg
    BROWN   Alexander   M   45   Farmer    Argyllshire       
    TURNER   Mary   F   80       Argyllshire       
    MCLEAN   Mary   F   10       Argyllshire       
    WIER   David   M   13   Male Servant    Argyllshire       
    BELL   Mary   F   15   Fem.Servant    Argyllshire

Mary McLean aged 10 must be Mary Ann Campbell McLean, daughter of Archibald McLean and Margaret Brown born 19 Oct 1831 at Inverchaolain.

Hope this helps
